The laser head is detachable, with a handle for handheld use. The long cable at the back facilitates mobility. A cage ensures consistent focus during handheld operation. While this feature may not be frequently utilized, it adds versatility to the laser’s capabilities.

Totalt sett, the B4 20W fiber laser maskin offers a comprehensive set of features and controls, catering to both beginners and experienced users alike.

Programvare & Protection

derimot, it’s beneficial to have both options available. Operating the laser requires the use of a computer, utilizing either the free software called EZCAD or the paid software called Lightburn, which entails a one-time fee of $150. As the user is accustomed to Lightburn programvare with all of his lasers, he will utilize it in this video as well.

Although the laser came with small metal sheets for testing purposes, he decides to use them as backing to conduct a material test engrave. This precautionary measure helps safeguard the work area in case of excessive heat or penetration through the metal. He recommends implementing this practice for every material to be engraved, as it streamlines the process and reduces guesswork.

For eksempel, he demonstrates engraving on a simple stainless steel card. The manual provides settings that can alter the color of the engraving on stainless steel, mainly by adjusting the frequency. He suggests having more examples for different materials would be helpful. på samme måte, he conducts a material test on an aluminum business card, which unexpectedly results in a hole being burned through it, emphasizing the importance of conducting such tests.

Dessuten, it’s imperative to ensure proper ventilation when using the laser, particularly when burning metals, to avoid inhaling harmful fumes. He employs ducting and inline fans to expel the exhaust outside. Emphasizing safety, he advises wearing eye protection while operating the laser.

3D Testing

The outcome saw some improvement but remained imperfect, as is often the case with trial and error processes. For individuals engaged in jewelry making or metalworking, the laser proves invaluable for marking designs and cutting metals, offering functionality similar to the templates previously designed. derimot, the laser’s capabilities extend beyond those of templates by simultaneously marking parts and adding intricate details. With its ability to engrave deeply, concerns about wear over time are alleviated.

Moving on to deep engraving, the potential of 3D engraving is explored, which presents numerous possibilities and is surprisingly easy to execute. Utilizing a 3D file of the desired design, sourced from platforms like Printables, conversion into an image format compatible with the laser is necessary. A free converter simplifies this process, producing a grayscale image that serves as a depth map for the laser. Adjustments to important settings ensure proper engraving, with power and speed settings varying for different materials. A screenshot of these settings can serve as a reference for tutorial purposes.

The most crucial aspect is ensuring the image mode is set to 3D sliced. I tillegg, ventilation is essential due to the generation of metal dust during the engraving process. Ved ferdigstillelse, the finished piece may be warm, requiring caution when handling. Detailed pieces can be obtained, as demonstrated with metal dust collection for potential reuse.

The versatility of the laser is further showcased by its ability to clean tools and remove rust, extending to larger objects when used handheld. Protecting the work area is simple, as the laser does not affect ordinary white paper. The high build quality and diverse capabilities of this laser setup make it a worthwhile investment, especially for business use. Despite its relatively high price tag of around $2,000 for the 20 W version, its longevity, with a claimed 100,000-hour lifespan, justifies its value, particularly for those utilizing it for profit.

cost performance of B4

De 20 W laser unit is priced at approximately $2,000. For individuals intending to utilize it for business purposes and generate income, this price is considered reasonable. Particularly when compared to alternatives such as the Laser Pcker 4, which typically falls within a similar price range but offers only a 20 W laser, the value proposition of the B4 laser becomes evident. Despite the nearly $500 price difference, the B4 laser’s 20 W power significantly surpasses the Laser Pcker, resulting in superior performance and considerable time savings during engraving tasks.

Drawing from personal experience with various laser models, it’s concluded that the Commarker B4 presents the best value for money at present. I tillegg, for users requiring even more power, the option of upgrading to a 100 W unit is available, albeit at a substantially higher cost of approximately $88,000. Nonetheless, as demonstrated, de 20 W laser is capable of accomplishing a considerable amount.

Links to all discussed products will be provided in the video description for viewers to explore further. Med det sagt, this concludes the video presentation.

derimot, he acknowledges that such power, allsidighet, og hastighet (opp til 10,000 mm/sekund) come with a significant price tag of approximately $55,200 USD at the time of recording. He expresses his intent to explore the capabilities of this laser and share his thoughts on it.

Expressing gratitude to Commarker for providing him with the machine for an honest review, he discloses the presence of affiliate links in the video description, which may benefit the channel if viewers choose to make a purchase based on his review. Nevertheless, he assures that his opinion remains unbiased regardless of any potential affiliation.

The introduction concludes with a reference to his previous videos, hinting at a continuity of content for viewers familiar with his channel.

Mopa’s Laser Principle.

You may have come across the review I conducted on the laser’s smaller counterpart, also named the Commarker B4 for some reason. derimot, this machine differs significantly. Not only is it physically larger than the other B4, but it also utilizes a different laser power source known as a MOPA laser, standing for Master Oscillator Power Amplifier. Without delving into intricate technicalities, unlike regular diode or CO2 lasers that primarily rely on speed and power for engraving and cutting, a fiber laser incorporates power, hastighet, and frequency to mark surfaces.

Med en MOPA fiberlaser, an additional adjustable feature called pulse duration is introduced. This provides flexibility in working with different materials by delivering high energy in potentially shorter durations, thereby minimizing heat generation. This feature is particularly beneficial for engraving delicate materials like certain plastics that are sensitive to high heat. Dessuten, it can produce more reliable color results on stainless steel and titanium. The MOPA laser also offers a wider frequency range, providing more options for marking materials.

In terms of construction, the machine is a single unit, unlike its smaller counterpart. It’s evident that this laser machine brings a host of capabilities and advantages due to its MOPA technology, setting it apart from traditional laser systems.

Machine Features

In terms of features, the machine offers versatility and ease of use. Attaching the included focusing bracket allows for straightforward operation by holding the handle on the top. While it can be handheld, it’s not exactly portable due to its weight and the need for a computer connection to operate. Although handheld operation isn’t planned, it’s appreciated to have the option available if needed.

The head of the laser features buttons labeled “R” for framing work and “M” for starting the job, providing convenient control options. I tillegg, there’s a power button, along with buttons for adjusting the vertical movement of the laser and an emergency stop button for safety.

The machine comes with two different lenses, altering the workable area. De 110 mm lens, installed by default, offers a workable area of approximately 110 mm x 110 mm. Switching to the 200 mm lens expands the workable area to about 200 mm x 200 mm, although with a larger and less powerful laser spot. Various interchangeable lenses, ranging from 70 mm to 200 mm, are available for further customization.

Two laser pointers in front of the lens aid in proper adjustment, ensuring convergence with the red laser at the correct focal height. A metal ruler provided by the company facilitates accurate measurement of the focal length. The base of the work area features spaced holes for screwing down angle brackets to secure workpieces. Optionally, these holes can accommodate a rotary tool for additional functionality.

An observation regarding the work area is the absence of pass-through holes seen in previous versions. I stedet, a metal plate has been added behind the holes to prevent debris from falling into the electronics below, indicating a design improvement for better maintenance and longevity.

Accessories and Specifications

The machine is accompanied by a box containing the driver for rotary tools, although a rotary tool itself is not included as standard. Different rotary tool designs are available for purchase as add-ons when ordering the machine. I tillegg, the B4 model includes a foot pedal, facilitating easier and faster operation of batch jobs. Spesielt, the machine comes with a pair of safety glasses and a laser shield, a welcomed addition that enhances safety during operation.

Operating as a galvo lasergraver, the laser head remains stationary while tiny mirrors within the head adjust to direct the laser beam. This design enables the machine to achieve remarkable speeds, reaching up to 10,000 mm/sekund. Available in various power options, inkludert 20W, 30W, and even 100W versions, the machine utilizes a JPT M7 MOPA laser source, known for its reliability and quality.

With a precision of up to 0.1 mm, the machine is capable of achieving extremely fine detail. As a fiber laser, it operates at a wavelength of 1064 nm, making it suitable for metals, plast, stones, og skinn, but unsuitable for materials such as paper and wood. The machine can be controlled using both the provided EZCAD software and Lightburn. derimot, til Lightburn programvare usage, a galvo license must be purchased separately.

Before delving into the jobs completed with the machine, it’s worth discussing the setup used during testing. This provides context for understanding the results showcased in subsequent demonstrations.

Innhegning

Lasers possess considerable power, capable of engraving metals by vaporizing the surface, creating metal dust. It’s imperative to have an effective fume or dust extraction system in place to avoid inhaling these particles. While Commarker offers an enclosure and fume extractor, their efficacy remains untested by the speaker. For personal use, the speaker constructed a small enclosure from a wooden box, initially crafted on another diode lasergraver. Secured to a base plate, the box features a top hole to accommodate the Galvo laser head. A latchable door at the front provides access, while a variable-speed fan aids in dust and fume extraction. Connected to a powerful inline fan, the setup efficiently removes particles to an outdoor filter. I tillegg, a camera is mounted inside for job monitoring, with a fin plate or heat sink underneath to dissipate heat and protect the work surface. Although this setup is detailed for informational purposes, alternatives may suffice depending on individual preferences. An SVG file of the enclosure is provided in the video description for those interested. The speaker’s initial exploration with the machine focuses on achieving colors on stainless steel.

rustfritt stål

Colors can be achieved on stainless steel using less expensive diode lasers, but the consistency obtained with the MOPA laser is unmatched. By joining the Laser Master Class and Commarker Facebook groups, the speaker discovered test files for marking color on stainless steel. Initially, a color swatch test found in the Commarker group was conducted using EZCAD to ensure the machine’s functionality, yielding satisfactory results. Subsequently, a Cadillac keychain test from the same group was executed, producing pleasing colors. To work primarily in Lightburn, the speaker replicated the EZCAD test values in Lightburn, ensuring parity between the two software. Additional tests and colors were explored based on findings from the Laser Master Class Facebook group.

The results revealed a variety of vibrant colors, albeit some being angle-dependent. Leveraging this knowledge, a color engraving of Mario’s head was created with adjustments made to achieve satisfactory results, except for the red in the hat. While the Mario image cannot be released due to copyright restrictions, a public domain Mickey Mouse file was utilized to demonstrate color engraving capabilities. With the same settings obtained from previous tests, a color version of Mickey Mouse was successfully engraved, showcasing impressive colors and detail. The Lightburn file for Mickey Mouse will be provided in the video description for public access.

Stainless Steel Tests

After feeling confident with the color settings, the speaker proceeded to conduct image tests on stainless steel. Employing similar values as the color test, a highly detailed image of a motorcycle was successfully engraved onto the metal surface. Further experimentation with the values is deemed necessary, as some results were heavily dependent on viewing angles, while others appeared too dark overall. Til tross for dette, the speaker expressed satisfaction with the overall outcome of the tests, acknowledging room for further tweaking and improvement.

Brass Coins 3D engraving

the speaker moved on to their favorite activity with fiber lasers: 3D gravering. This process involves converting a 3D model into a height map, which can be sliced in Lightburn, similar to how a 3D printer operates. For this task, a brass coin blank purchased from Amazon was utilized. Initially, a highly detailed file sourced from the Laser Masterclass Facebook group was attempted, although it proved almost too intricate upon completion. Subsequently, a file specifically designed for this purpose, acquired from Etsy, was employed with the same settings, yielding impressive results. The speaker expressed enthusiasm for 3D engraving due to its capability for intricate detail.

Dust removal was emphasized as essential during 3D engraving, given the pulverized material generated during the process. Moving on from coins, the speaker conducted an aluminum business card test, a task well-suited for fiber lasers. The machine’s included material pack contained such cards, among other test products, with a thickness of almost half a millimeter. The speaker successfully engraved a dog image onto one of these cards using Lightburn, achieving excellent results.

With the engraving tasks completed, the speaker expressed an interest in trying card cutting next.

Card Cutting

For the card cutting experiment, the speaker decided to test the machine’s power by cutting a design out of a card. They utilized an image of an eagle purchased from Etsy and applied the same settings used for engraving, followed by a cutting operation. The cutting was executed at a speed of 2500 mm/s, med 100% makt, en 60 kHz frequency, 200 nond C pulse, og 1500 passerer. Given that Lightburn has a maximum limit of 500 passerer, the job was run three times consecutively to achieve the desired result. The speed was indeed remarkable, with the footage capturing the process without any alterations. derimot, the camera accidentally obstructed the laser during filming, prompting the speaker to consider incorporating the residual parts into the design as a stand for the artwork. Subsequently, they intentionally left a tab in the design for this purpose, which proved successful.

I tillegg, the speaker conducted another test where the cut was fully removed from the card, yielding satisfactory results. Endelig, the last test performed on the machine involved experimenting with plastic, although they acknowledged the need for further tests in this regard.

Plastics Testing

In the plastic tests, the speaker aimed to gather data on various materials to establish a comprehensive catalog of settings. Although further experimentation is required, the initial outcomes show promise. They conducted tests on different materials to assess their suitability. Two tests were conducted on travel power bricks, both utilizing identical settings. derimot, the results varied significantly: one appeared white, while the other appeared dark. This discrepancy demonstrates that the type of plastic used greatly influences the outcome of the markings.

Conclusion

Totalt sett, the speaker expressed satisfaction with the performance of the machine. They acknowledged that working with fiber lasers, especially those with MOPA functionality, may have a steeper learning curve compared to standard diode or CO2 lasers. derimot, for tasks such as metal marking, gravering, or cutting, fiber lasers offer significant advantages. They emphasized the valuable learning resources available on platforms like the Laser Everything YouTube channel, which provides tutorials and power-speed libraries for beginners.

Regarding cost, the speaker noted that while the reviewed 60W MOPA laser is not cheap, there are options available with lower power and without MOPA capabilities that could be more affordable for those with different needs. They highlighted that the choice ultimately depends on the specific requirements of the user.

Avslutningsvis, the 60W B4 MOPA laser from ComMarker is recommended for those seeking MOPA functionality and features such as consistent colors on stainless steel and a wide range of shades on different plastics. The speaker expressed gratitude to ComMarker for providing the machine for an honest review and invited viewers to explore affiliate links in the description for further support. They closed by thanking the audience for watching, encouraging engagement with the content, and promising more videos on lasergraver, 3D printing, injection molding, and other maker-related topics in the future.

All right, welcome back to the Redbeard Ops Workshop . I dag, he is going to be reviewing a fiber laser from ComMarker. He had seen some other YouTubers using ComMarker B4 lasergraveringsmaskin , and that gave his the confidence to collaborate with ComMarker for a review from the perspective of a knife maker. As you all know, he has reviewed the Xtool 20W diode lasergraver in the past, and he will be getting into what differentiates these two laser machines later in the video.

While putting the machine together, it’s impaortant to note that these lasers are not toys and can cause damage to your eyes or lungs, depending on what you’re engraving. The laser comes with a set of protective glasses, but they ended up ordering another set that is certified and will protect them with both lasers in their shop since they have different wavelengths. The 190nm to 550nm range will cover the diode laser, and 800nm to 1100nm will cover this fiber laser. I tillegg, he emphasizes the importance of keeping the shop ventilated and potentially using a fume extractor if engraving toxic materials or working in high volumes.

As you just saw, the assembly was very straightforward, especially in contrast to putting together the Gantry on the Xtool diode laser. The only movement this fiber laser has is in the Z-axis in order for a user to focus it.

Preliminary Understanding

RedBeardOps hadn’t been satisfied with the quality of the plastic fences that came with ComMarker B4. Følgelig, he took it upon themselves to design replacements using Fusion 360, intending to print them out on their Bamboo Labs P1S. I tillegg, they designed a 3D printed stand for the rotary attachment, which they planned to attach to the laser bed since it tended to hang off the side during use. They mentioned that free links to these print files would be included below in the description.

ComMarker B4 includes a USB stick with the necessary drivers and a copy of ezcad to facilitate setup. derimot, as RedBeardOps is already a Lightburn user, he opted to upgrade to the galvo version of Lightburn programvare, which is required for fiber lasergraver . Although he decided not to delve into the mundane details of computer setup, he indicated that an installation guide link would be provided in the cards and/or description below.

Before proceeding with knife steel depth testing and maker marks on knives he cared about, RedBeardOps wanted to acquaint themselves with commarker b4 lasermarkeringsmaskin .

In the segment about laser bed alignment, RedBeardOps mentions that the ComMarker lasergraver cames with a pack of sample materials, such as business cards and dog tags, which are suitable for testing purposes. He quickly noticed that his laser wasn’t aligned with the fences. For å løse dette problemet, he lined up one of the business cards with the fence and etched a horizontal line on it using Lightburn software . Adjusting the alignment was a simple process that involved loosening the column bolts and gently turning the column counterclockwise within the tolerance of the mounting holes.

He then experimented with the settings using a chrome dog tag from the sample pack. After some trial and error, he found the optimal settings that resulted in a dark and deep etch into the dog tag. He emphasize that achieving the desired results often requires experimentation and sacrificial materials.

Feeling confident after successfully etching the dog tag, they express their intention to personalize some tools, which they believe can be useful not only as gifts but also for keeping track of tools in a multi-person environment.

RedBeardOps acknowledges an issue with the Red Dot preview frame not lining up with the final result on steel. Although he resolved this issue after shooting most of the footage, he mention that there is a software solution in Lightburn settings to offset the frame, ensuring accurate alignment.

Endelig, he remark that the laser performed well in etching both brass and aluminum materials.

Materialtesting

Messing & Aluminium

In the discussion about etching brass and aluminum, RedBeardOps expresses his impression with the laser’s performance, particularly in etching these materials deeply. He notes that he has observed others using the fiber laser for etching brass coins, which leads him to believe that with enough time, it could be utilized for creating custom brass leather stamps or similar items.

RedBeardOps mentions the simplicity of focusing the laser using the Z-axis motor, where one aligns the material on the bed and adjusts the laser head until the three dots overlay each other. He demonstrates this process by etching his vice jaws to showcase the laser’s performance on aluminum. I tillegg, he intends to incorporate some branded elements into the background of his hand sanding footage using commarker b4 fiber lasergraver .

Moving forward, He expresses his  intention to continue testing different materials and settings with commarker b4 20w lasermarkeringsmaskin .

Lær & Tre

When discussing etching on leather and wood, RedBeardOps mentions that a fiber laser engraving machine  is not particularly suited for these materials. Its higher wavelength makes it ideal for metals, but it tends to underperform compared to a diode laser when it comes to natural soft materials. Although some people have achieved success with leather etching using a fiber laser, RedBeardOps believes it requires a significant amount of time to fine-tune the settings. He demonstrate their experimentation on a test piece, showcasing a range of light to ultra-dark marks.

I tillegg, He notes that the performance on wood is also subpar. For those interested in etching wood and leather, RedBeardOps recommends opting for a diode laser like the 20W Xtool, which he has previously reviewed on his channel. This recommendation extends to cutting applications as well. If one intends to cut out sheath templates or custom wood boxes, a diode laser is the preferred choice.

Before transitioning to knife steel testing, RedBeardOps highlights the rotary tool and its functionality.

Rotary Tool(Tumler)

When discussing the performance of the fiber laser on tumblers, RedBeardOps highlights his popularity for engraving purposes, whether as gifts or for creating custom merchandise for shops. He recounts spending hours figuring out the right settings for Yeti tumblers on the machine and hope that sharing his insights will assist others looking to undertake similar projects. Noteworthy is the mention of focusing the laser at the apex of the cup and employing a small split on the rotary tool settings. He also mentions running multiple passes at lower power to avoid marking the underlying stainless steel and only burn off the powder coat. He emphasizes  the importance of proper ventilation when using the laser in the shop.

Regarding the potential rotary application for knife making, RedBeardOps speculates that it could potentially be used to engrave pommel nuts but admits to drawing a blank on other potential uses in the shop. He invites viewers to share any ideas they may have in the comments section.

Avslutningsvis, RedBeardOps indicates that they have now familiarized themselves with the machine and are ready to proceed with their planned activities.

Knife Steel Initial Testing

In the process of testing knife steel with the machine, RedBeardOps begins by taking a piece of 104 bar stock and initiating test grids for speed and power using Lightburn’s built-in testing panel. He mention the ability to vary the interval and frequency for fiber lasers, starting with a general spot. Subsequently, they commence running iterations of their maker mark on the test piece to evaluate the sample etches.

After completing the etching process, RedBeardOps transfers the bar to his sanding bench and removes the soot around the edges with sandpaper to assess the depth of the etch. Noticing that the first batch of marks was washing out, they realize the need to increase the laser duration with multiple passes. They point out running a relatively low power setting to avoid edge discoloration around their mark, though they acknowledge the necessity for further testing to confirm this theory.

Upon completing the second batch of maker marks, RedBeardOps is pleasantly surprised by the improved outcome, particularly noting the cleanliness and depth of the third mark. They express their astonishment at the quality achieved and hint at further testing in the future to refine their process.

Depth Testing VS Electro Chem

In order to provide a comprehensive comparison, RedBeardOps decides to conduct depth testing between the fiber laser, their normal electrochemical etching method, and the diode laser. He explains their methodology, which involves etching small rectangles onto a piece of stainless steel using Lightburn software for the lasers. For the fiber laser, they run tests at both 10 og 20 passerer, noting the time taken for completion. He observes that during the longer etching cycles, the bar stock becomes slightly warm.

For the diode laser, He adjusts the size of the rectangle to save time, as it etches slower than the fiber laser. Despite running it at 90% power and 5 mm/sekund, the diode laser yields shallow etches compared to the fiber laser.

Upon inspection, he expresses slight surprise at the depth achieved by the diode laser, noting that previous tests on carbon steel resulted in a darker finish. They proceed to compare the results with those obtained from their DIY electrochemical etching machine, which typically produces deep and dark etches.

After performing the tests, they clean the test bar with sandpaper and measure the depths of the etches. The 10-pass fiber laser etch reaches a depth of approximately 1/2 thousandth of an inch, while the 20-pass etch reaches 1 og 1/2 til 2 thousandths of an inch. I kontrast, the diode laser etch does not register any significant depth, and the electrochemical etching machine achieves a depth of around 2 og 2 thousandths of an inch.

Totalt sett, RedBeardOps finds the results from the fiber laser promising, as additional passes could easily increase the depth if needed. They conclude by acknowledging the depth achieved and expressing satisfaction with the laser’s performance.

Etching KNVIES

With the knowledge gained from their previous tests, RedBeardOps proceeds to etch actual knives. They mention a recent buoy build where they used the laser to imprint their maker mark on the ricasso. Expressing satisfaction with the ease of alignment and the etching performance, they note running 20 passes on the mark but wish they had done a few more for a slightly deeper etch. Til tross for dette, they consider the mark acceptable.

They then turn to an old knife they made based on Knife Talk build-along plans, using it to compare the fiber laser mark with an electrochemically etched one. After cleaning the knife’s side without the electrochemical mark, they etch it with the fiber laser using 20 cycles, consistent with previous tests. Upon inspection with a digital microscope, they note significant differences in precision and cleanliness between the two methods.

Impressed by the fiber laser’s performance, RedBeardOps considers various applications such as labeling materials used in builds, personalizing blades for customers, or leaving hidden messages on knife internals. They express excitement about the machine’s capabilities, which they plan to use for etching their maker mark in future work, replacing their electrochemical etching machine.

To conclude, they provide affiliate links to the laser and free 3D print files mentioned earlier in the video and invite suggestions for future laser experiments or improvements in settings. Endelig, they express gratitude to ComMarker for providing the machine ComMarker B4 20w laser engraver  for review and for use in his workshop.

Commarker also thanks Redbeard Ops Workshop for being willing to share the adaptation he made with us. If you want to learn more experience with engraving tools, you can click on this link to consult Redbeard Ops Workshop   https://www.youtube.com/watch?v=rRrAhYeloCc 

What’s Rust

Først, he explained to us what rust is, and he intends to use a Commarker B4 fiber laser graveringsmaskin for rust removal.

Rust is a reddish-brown or orange-yellow substance that forms on the surface of iron or steel objects due to a chemical reaction between iron and oxygen, commonly known as oxidation. nærmere bestemt, when iron reacts with oxygen, it forms compounds known as iron oxides. This process is often accelerated in humid environments where water can speed up the oxidation of iron. Rust typically appears as a powdery or flaky substance covering the surface of iron or steel objects, giving them a corroded appearance. It not only affects the aesthetics of the metal but can also lead to a loss of strength and durability. Derfor, preventing and treating rust is crucial for preserving the quality and longevity of iron or steel objects.

Principle of laser rust removal

The principle of laser rust removal is based on the high energy and high focusing properties of lasers, as well as the optical characteristics of the oxide layer and the metal surface. The main principles include the following:

1. Optical absorption: When a laser beam is directed onto the surface of a metal, the oxide layer (such as rust) absorbs the energy of the light because of its darker color, making it more prone to absorbing light energy.

2. Thermal effect: The absorbed light energy causes the oxide layer to rapidly heat up. Once reaching high temperatures, the oxide layer begins to decompose or evaporate. This high temperature causes the oxide layer to detach from the metal surface and be evaporated or ejected under the action of the laser beam.

3. Optical selectivity: Laser beams can be highly focused, allowing precise control of the area affected by the laser. This means that the laser energy is concentrated only on the oxide layer to be removed, without causing damage to the metal surface.

oppsummert, laser rust removal utilizes the high energy and focusing properties of lasers to precisely concentrate light energy on the oxide layer on the metal surface. This results in heating, decomposition, or evaporation of the oxide layer, achieving cleaning and rust removal without damaging the metal itself.

Thermal Expansion

Thermal expansion occurs when subjected to high temperatures due to the energy, although this happens on a microscopic scale, hence why the metal doesn’t visibly melt. The intense heat also induces thermal expansion in the rust at a significantly faster rate than the underlying metal. This discrepancy in expansion, coupled with the extreme heat, causes the rust to break its bond with the metal surface. Subsequently, the rust particles can either vaporize or be forcefully ejected from the surface. By fine-tuning the laser settings, one can target the rust layer without causing damage to the underlying metal. When using a fiber laser, three primary parameters can be controlled: hastighet, makt, og frekvens. Fiber lasers have the capability to produce very high peak powers, reaching tens of kilowatts, by concentrating the energy delivery into short, rapid-fire pulses. Even low-powered fiber lasers can effectively remove rust layers through a series of micro-explosions generated by the rapid pulses. These quick pulses help prevent overheating of the underlying base metal. For rust removal, it is advisable to use low-frequency settings, as higher frequencies may not deliver enough energy to induce ablation on the surface.

Konklusjon

Avslutningsvis, it is advisable to also use low power at low frequencies, as high power at low frequencies may not be optimal for the components inside the fiber laser. I tillegg, it is recommended to set up a fume extractor to remove the generated fumes. Here are some of the attempts made using the 20W fiber laser from Commarker. The settings used will be displayed over the video to demonstrate the contrast between rust removal using sandpaper and laser. This showcases the effectiveness of removing rust using a fiber laser.

Victorius Garage forklarer at valg av commarker b4-modell innebærer å velge deksel, galvo system, og fiberlevering. Den spesifikke kilden som er plassert inne i maskinen er opp til brukeren, alt fra 20W til 60W fiberkilder eller en jpt mopakilde. Victorius Garage bemerker at maskinen har et industrielt preg og kommer med to sett med linser, gir mulighet for justeringer i arbeidsområdet. Til tross for at den ikke kan skryte av eksepsjonell byggekvalitet, den tilfredsstiller vertens krav, as he prioritizes internal components over external features.

Victorius Garage berømmer presisjonen til galvo-systemet, men kritiserer den medfølgende programvaren, EZcad , som underpr, foreslår at seerne velger LightBurn programvare med sin $140 lisensavgift. I tillegg, maskinen tilbyr muligheten til å inkludere en roterende akse, som rommer forskjellige roterende akser på grunn av sin kompatibilitet med standard trinnmotorer. This flexibility allows users to customize accessories for manipulating the working area.

Verten Victorius Garage fremhever den motoriserte tårndelen for justering av laserhøyden og nevner det avtakbare hodet. Han forklarer at mellom kilden og galvosystemet ligger en optisk fiber som overfører laserkraft. He concludes by expressing his intention to connect the machine to a computer to demonstrate its power and capabilities.

Effekttestingen av ComMarker B4 20watt

Den enkelte er på kontoret, med laseren plassert som vanlig, pyntet med klistremerker fra tidligere Instagram-videoer. Victorius Garage fortsetter å gjennomføre en krafttest på en 316 rustfri stålplate. Victorius Garage fremhever LightBurns evne til å kjøre materialreaksjonstester, gi innsikt i potensielle resultater og merke dybde før endelige eksperimenter. Bekymret for kamerasikkerhet på grunn av laserens intensitet, they emphasize the importance of avoiding sensor damage.

Forklare fokuseringsprosessen, de nevner å justere to punkter til de krysser hverandre, sikre optimalt fokus. Victorius Garage legg merke til LightBurns allsidighet i testmønstre, velger å undersøke frekvens kontra effekt. Ved å endre frekvens og laserkraft, Victorius Garage har som mål å vise frem resulterende merkevariasjoner. Til tross for prosessens intrikate, de setter hastigheten til 100 mm per second for clarity.

Victorius Garage diskuterer farge på rustfritt stål, påvirket av effekt- og frekvensjusteringer. Skifter fokus til maskinens detaljerte egenskaper, de undrer seg over de intrikate detaljene som kan oppnås. Spesielt, de fremhever justeringspresisjon mellom forhåndsvisnings- og markeringslasere, avgjørende for nøyaktighet. De uttrykker ærefrykt for maskinens oppløsning og detaljer, noting the challenge of capturing its full splendor on camera.

Den enkelte konkluderer, intending to conduct further tests.

Materialtesting for Commarker B4 lasergraver

I aluminiumstesten, laseren blir testet i superraske hastigheter. Den er satt kl 300 mm per sekund i utgangspunktet, og deretter økt til 500 mm per sekund for å observere kvaliteten på merkingen ved disse hastighetene. Galvo-systemet er kjent for sin evne til å nå høye hastigheter uten problemer. Testen er ytterligere eskalert til 1000 mm per sekund, avslører en liten degradering i merkets klarhet, foreslår en grense for dette materialet rundt 600 mm per sekund. Til tross for dette, markering kl 600 mm per sekund gir fortsatt resultater av høy kvalitet, ideell for aluminiumsmerking. Tillegg av en roterende akse er nevnt, og det er gjort et forsøk på å gravere en ring for å teste kameraets fokuseringsevne. Den generelle ytelsen til maskinen får ros, spesielt kraftuttaket. Det er et uttrykt ønske om å undersøke fiberkilden som er innlemmet i maskinen, prompting the decision to open it up for inspection.

Når det gjelder forbindelser, maskinen ser ut til å være godt laget basert på observasjoner. Alle koblinger er utstyrt med varmekrympe, inkludert de for krymping av DC-motoren for å kontrollere Z-aksen. I tillegg, det er en logo som indikerer tilstedeværelsen av en Max Photonics-kilde, som regnes som en høykvalitets laserkilde. Fiberen kommer ut fra dette punktet, fører til hodet, som også er pent ferdig. Tatt i betraktning at det er fra en oppstart, produktet er prisverdig. Både speilene til galvosystemet og laserkilden ser ut til å være av god kvalitet. Kvaliteten på disse komponentene bestemmer til syvende og sist laserens levetid, particularly regarding their reflectance at the infrared wavelength.

Går videre til testing, et forsøk på å gravere et plastverktøysett, resulterer i et vakkert merke. Det bemerkes at effektiviteten av merking avhenger av typen plast, og akkurat denne reagerer godt på infrarød merking, etterlater et dypt merke uten å forårsake forbrenning. Overgang til en demonstrasjon av rå makt, et stykke rustfritt stål utsettes for høy kraft og langsom bevegelse, resulterer i betydelig deformasjon på grunn av den intense varmen som genereres. Varmen er merkbar, indicating the effectiveness of the machine’s power output.

Endelig mening fra kommentator B4

Victorius Garage bestemmer seg for å avslutte anmeldelsen på dette tidspunktet, uttrykker sin betydelige overraskelse med maskinen. Han har brukt en måned på å eksperimentere med merkelappen B4 20watt fiber laser markeringsmaskin , jevn kutte sjablongark av 0,1 mm rustfritt stål, brukes vanligvis til sveisemasker og lignende applikasjoner. Han synes maskinen er bemerkelsesverdig. Hovedpoenget de tar sikte på å formidle med denne anmeldelsen er ektheten til den 20W nominelle kilden den kommer med, fremhever det vanlige bedraget i laserindustrien angående strømspesifikasjoner. De presiserer at mens maskinen bruker 400W, den faktiske laserutgangseffekten er bare 20W, som er det avgjørende aspektet. Å være en pulserende fiberlaser, it’s capable of generating significantly higher-energy pulses.

Victorius Garage anbefaler denne maskinen på det sterkeste, spesielt sammenlignet med andre som LaserPeker, avhengig av tiltenkt bruk. For produsenter som er involvert i dekorative prosjekter, en brukervennlig programvare som Laserpeker vil være å foretrekke. derimot, for verksteder som krever massegravering, en maskin som denne, med vekt på kraft og hastighet, ville være mer egnet, selv med den ekstra kostnaden for en $140 LightBurn-lisens. De hevder det når det gjelder verdi for pengene, det er ingen konkurranse, som å anskaffe 20W fiber for $1999, inkludert viktige komponenter som galvo diode laser system og kontrolltavle, er svært konkurransedyktig. Slik, avslutter han anmeldelsen, leaving the audience eagerly anticipating the next video.

Having primarily tested lasergraveringsmaskin med 20 watts or lower power previously, the speaker acknowledges the significant increase in power and the potential benefits it brings in terms of speed and cutting depth. They speculate on potential applications for this increased power.

The speaker comments on the upgraded safety goggles provided with the new model and observes the considerable weight and size of the machine. They note that despite its bulk, the machine is efficiently designed, with all necessary components neatly integrated into the base plate assembly.

Assembly is straightforward, with just a few screws connecting the various components. The speaker appreciates the manufacturer’s openness to inspection, noting improvements in the assembly compared to the previous model.

Avslutningsvis, the speaker expresses satisfaction with the machine’s assembly and readiness for use, only ten minutes after unpacking. They anticipate further exploration through teardown.

A preconfigured ezcad2 lite software copy is provided on a USB stick, instantly ready to use. It operates silently in standby mode, with fans only spinning up during longer, higher-power operations. The narrator reflects on past skepticism regarding the Z-axis power feed through a DC gearbox motor due to difficulties with the hand crank on the tall machine. derimot, they now consider power feed justified, suggesting that a stepper motor could further enhance performance by automating deep 3D engraving operations.

The narrator discusses the machine’s large height, noting the need to account for the standard field lens with a 200 mm focal length. They highlight the potential for utilizing the machine’s height to expand the working area with an optional field lens featuring a 380 mm focal length. Despite the advantages of the tall machine, the narrator opts to continue using a smaller area lens for the time being to achieve the smallest focal point diameter.

I tillegg, the narrator mentions learning new techniques and optimizing scan speeds for efficient engraving. They acknowledge the manufacturer’s specification of a high scan speed of 10,000 mm/s and aim for a more manageable 7,000 mm/s. The narrator shares the parameters for image engraving on coated or anodized metal parts, emphasizing the machine’s ability to produce stunning results.

Dessuten, they discuss the advantages of using a powerful pulsed infrared laser for engraving various materials, including bare metals. The narrator proposes a method for achieving high-quality engraving on uncoated metals, highlighting the machine’s fine control over average power and impulse timing.

Avslutningsvis, the narrator acknowledges the trial and error involved in finding optimal parameters for different materials and desired looks. They express the need for more resources on the internet regarding working parameters, particularly for color engraving on stainless steel.

Colored markings on Stainless Steel and titanium

Among the headline features of the product, present significant challenges in achieving the desired outcome. The process involves thermally growing a surface oxide layer, the thickness of which determines the color effect. Even a slight difference in thickness, on the order of tens of nanometers, can result in drastic changes in apparent colors. Derfor, every variable, including field lens substrate thickness, brennvidde, alloy variations, and ambient temperatures, must be carefully considered.

Despite the existence of material test grids available online, they may not be particularly helpful due to the numerous variables involved. I stedet, systematic testing with a significant amount of material is often necessary to achieve the desired results. derimot, for products with consistent properties, such as mass-produced items, investing time in perfecting the settings for the ComMarker B4 Laser engraver machine may only be required once.

For high-value, unique products like custom knives or artisan woodworking, finding optimal settings may take around an hour with some experimentation. The thin film interference responsible for the color effect theoretically allows for the creation of every color in the visible spectrum. derimot, in practice, achieving certain colors, particularly pure red, can be challenging, with many shades tending towards brown or olive. I tillegg, the appearance of colors can be viewing angle-dependent.

Nevertheless, the ability to create colored markings is both fascinating and immensely useful. Despite the challenges, the capability of the product continues to impress, promising further advancements in the future. Optional features may offer additional functionalities, enhancing the product’s versatility.

Rotary axis and Auxiliary Holder

The B4 fiber laser engraver offers users the option to include a rotary axis for an additional cost of $250, with a current $50 extra fee. This addition brings several advanced functionalities to the machine, enhancing its versatility and capabilities.

Included in the rotary axis package is an advanced JCZ controller card prepared with iOS, providing users with an additional motion axis for more complex engraving tasks. I tillegg, an external stepper motor driver is provided, which conveniently plugs into the rear of the engraver. The physical third axis, essentially a chuck attached to a stepper motor, adds a new dimension to engraving possibilities.

Despite the potential advantages of the rotary axis, some users may find themselves not utilizing it frequently. derimot, in certain contexts, such as jewelry engraving, the rotary axis can prove invaluable, allowing for personalized engravings on items like wedding rings and jewelry engraving.

An interesting feature included with the holder is a focusing aid, enabling users to add a fixed distance ring to the head for handheld operation. While this feature may not be utilized regularly, its presence adds to the machine’s versatility.

Dessuten, the holder comes equipped with a convenient handle and a manual fire button on the head. These features, while impressive, also evoke a sense of caution due to their potential for complexity and the need for careful operation.

Avslutningsvis, the rotary axis is an optional addition to the B4 fiber laser engraver that offers advanced functionalities and expanded engraving capabilities. While some users may not utilize it frequently, its presence adds value to the machine, particularly in specialized applications like jewelry engraving. I tillegg, the included features such as the focusing aid, håndtak, and manual fire button further enhance the machine’s usability and flexibility.

ComMarker B4 Mopa-JPT M7 Laser source

Modifications have been made to the machine, with further considerations before pushing it to its limits. The thread grid plate still employs through holes, which are easy and inexpensive to manufacture. derimot, when ablating metal parts, especially conductive dust, can fall through these holes and potentially enter the laser source through its cooling system or come into contact with the controller card or mains power supply. A plate with blind holes would be preferable, albeit more costly. An easy fix for this issue can be applied either by the manufacturer or by the customers themselves, as outlined in the manual for JP’s M7 fiber laser.

According to the manual, the bend diameter for the beam delivery cable must be at least 15 cm to prevent power loss in the fiber. The com marker team has taken note of this requirement and arranged the coil accordingly. derimot, the section where it bends around the corner is too tight for the narrator’s preference, prompting them to reroute it slightly.

Totalt sett, the construction of the machine has improved compared to previous iterations, though it may not be considered world-class. Nonetheless, considering the machine’s price point, which is only $500 more than a 20-watt more from a competitor while being three times as powerful nominally, it offers great value. I tillegg, the machine’s laser power exceeds its average output power slightly, as verified by an OFIER L3C continuous wave power sensor.

The machine was delivered with a test certificate from one of the most reputable fiber laser source manufacturers in China, specifying an operating lifespan greater than 100,000 timer. Although it’s challenging to prove this claim, given that the M7 model hasn’t been around for 11 år, since it’s a complete solid-state system, it instills confidence in its durability and longevity.

Laser protection

The narrator emphasizes the importance of safety when operating the machine, noting that it far exceeds the requirements for a class 4 laser. They highlight the necessity of implementing numerous safety features to ensure safe operation by humans. derimot, they mention that the ComMarker B4 fiber laser maskin lacks significant safety features, allowing the manufacturer to offer it at a lower price than Western standards.

They caution viewers against operating the machine openly, suggesting instead that it should be treated as a component for building a safe machine oneself. Despite this warning, the narrator admits to taking risks by filming without a fully enclosed opaque box to capture more visually interesting footage.

To mitigate some risk, the manufacturer has included a freestanding orange acrylic shield and a pair of safety goggles, which are of higher quality than typical green plastic ones. derimot, the narrator expresses reservations about the reliability of these safety accessories, as they lack visible markings or manufacturing information.

While acknowledging that both the shield and the goggles provide some level of infrared attenuation, the narrator remains cautious, particularly regarding the goggles’ effectiveness without a well-known brand name. Despite these concerns, the narrator proceeds with their experimentation, noting one additional observation about the machine’s performance.

Pulse width measurement

The narrator discusses an opportunity for improvement concerning pulse width measurement in the B4 machine, focusing on its head and Galvo scanner. They note that the only audible component in standby mode is the red preview laser pointer, which they couldn’t disable. Typisk, disabling the red pointer is possible with a JPT M7 source, enabling cleaner readings with a photodiode. derimot, the B4 employs an external additional laser diode and a dichroic beam combiner, unlike the JPT M7 source.

The advantage of this setup is that the red pointer remains on continuously, whereas the JPT pointer is mutually exclusive with the power output. Despite this advantage, the narrator plans to remove the setup due to a microscopic offset between the preview point and the actual working beam, which may affect measurements.

To address pulse widths in the nanosecond and below range, the narrator attempts to use a $50 indium gallium arsenide photodiode with a sub-nanosecond rise time. derimot, they encounter difficulties in building a trans-impedance amplifier for accurate measurements due to the need for gigahertz PCB designs and specific components.

I stedet, they opt for reverse biasing the photodiode with batteries and digitizing the current impulses through a 50-ohm resistor and coaxial cable to the scope. While this setup is adequate for confirming pulse widths in the sub-nanosecond range, it lacks the finesse required to observe peak output power waveforms.

Despite the challenges, the narrator remains determined to continue experimenting with the machine, noting that they will focus on more enjoyable activities now that the initial work is complete.

Fiber Laser Marking machine – Materialtesting

In the realm of Cu sheet cutting, the narrator expresses enthusiasm for the revolutionary capabilities of the machine in their lab. They anticipate releasing videos to their Patreon and channel members to showcase the purpose of copper shims. I tillegg, they discuss their plans for wire welding, aiming to construct a resistance standard from a nickel-chromium alloy wire. derimot, they encounter challenges due to the thinness of the wire, leading to difficulties in spot welding.

Moving on to plastic welding, the narrator experiments with welding thicker materials using the pulsed laser function of the JPT M7 source. Despite initial skepticism, they achieve satisfactory results after a few attempts. derimot, they opted not to pursue further experiments due to the unpleasant odor associated with plastic welding.

Transitioning to stainless spot welding, the narrator demonstrates successful spot welding on stainless steel sheets. Despite encountering initial challenges, they achieve strong welds, highlighting the ease of the process.

Continuing their exploration, the narrator delves into intermetallic welding, attempting to solderable pins in a blue glass seal. They employ a pulsed operation with kilowatt power bursts to weld copper, sølv, gull, and steel. Although the results are not flawless, they acknowledge the mechanical strength of the welds achieved in their third attempt.

Thanks again to Marco Reps for sharing with us his experience and guidance on the ComMarker B4 jpt mopa 60w lasermarkeringsmaskin. https://www.youtube.com/watch?v=D-sTbr1ZuEU

comMarker was kind enough to send over their b4 20W fiber lasergraver for the individual to check out and make a video about it. If the reader isn’t familiar with what a fiber laser is, it’s essentially a type of laser that can engrave onto metals. derimot, it’s not limited to just metals, as demonstrated in the video. The fiber laser is capable of engraving extremely fast with impressive details. The real-time engraving shown in the video isn’t sped up whatsoever, which is quite impressive for only 8 seconds.

Some assembly is required with this laser, but everything needed comes in the box, including a secondary lens. The choice of lens determines the size of the work area and accuracy, making it a valuable addition. I tillegg, comMarker included a handful of test materials, ensuring the user has something to use and test out to familiarize themselves with the laser.

All parts of the laser are made out of metal, providing a sturdy and durable feel. After assembling everything, the user found the instruction manual to be pretty good, making the setup process easy to follow. Endelig, here it is, all set up and ready to go.

Ærlig talt, the b4 lasergraver has a pretty small footprint, especially when compared to a 50W laser, which takes up more room and requires its own cart for mobility. The b4 laser engraver comes in 50W and 60W options with the same compact form factor, providing users with extra power if needed.

Looking at the front of the machine, it features simple controls including an emergency stop button, which immediately cuts power to the machine, and the main power button. I tillegg, there are focus controls to adjust the laser head vertically for precise focusing. Despite being powered, the movement of the laser head is slow, aiding in achieving perfect focus.

The machine also includes laser guides to assist in focusing on the material being engraved. These guides converge to one point, aided by laser pointers under the laser head. The focus point can be adjusted using millimeter measurements on the side of the machine. Instructions for adjustment are provided in the manual, along with details on adjusting the focus point for different lenses.

Two buttons on the front of the laser head activate the red lights or start the laser engraving process without the need for a computer. The laser head is detachable for handheld use, facilitated by an extra-long cable and a protective cage around the lens.

Applications for the Commarker B4 laser engraving device.

Operating the laser requires a computer with ezcad or lightburn software , the latter being a one-time fee of $150. Test materials are provided, but using additional backing materials during engraving is recommended to protect the work area.

For eksempel, a stainless steel card can be engraved using settings provided in the manual, which can change the engraving color by adjusting the frequency. Similar tests on an aluminum business card revealed the importance of using backing materials to prevent damage to the workpiece.

When using this laser, it’s important to ensure proper ventilation, particularly because it involves burning metals, which could emit harmful fumes if inhaled. The user sets up ventilation using ducting and inline fans to exhaust the fumes outside. Safety goggles are essential to protect the eyes from potential hazards, and since the laser came with a pair, the user opts to use those.

The build surface of the laser engraver features numerous threaded holes, allowing for the mounting of guides to ensure consistent positioning of parts. For batch orders, a foot pedal is provided to start the laser, allowing for hands-free operation. Despite using manual initiation for demonstration purposes in the video, the foot pedal offers convenience during bulk processing.

This type of laser enables vector line work as well as grayscale images, albeit with some trial and error to determine optimal settings for different materials. Even with imperfect tuning during engraving, satisfactory results can be achieved, although adjustments to power settings may be necessary.

In addition to engraving, the laser can add or remove markings from various materials, though the removal process may not be entirely clean. derimot, adding markings to clean surfaces, such as demonstrated on a brass part, can lend a professional touch.

The laser can be used on 3D-printed parts to add finishing details, giving them a more polished appearance. It offers an advantage over traditional methods, particularly in jewelry making or metalworking, where it can mark designs for later cutting. The rotary tool attachment allows for engraving on round objects, with options for different setups.

Despite some initial challenges in achieving desired results, the laser offers versatility in marking complex shapes and adding detailed engravings. Its deep engraving capability ensures longevity, while its gentle cleaning ability allows for rust removal without damaging tools.

Protecting the work area during operation can be as simple as laying down a piece of white paper, as the laser won’t affect it. Totalt sett, the laser setup proves to be of high quality with diverse applications, promising longevity with a claimed lifespan of 1,0000 hours.

Commarker B4 low-cost laser engraving machine.

derimot, this tool comes with a significant price tag, priced at around $2,000 for the 20W laser. Despite the cost, if it’s intended for business purposes and to generate income, the price may be justified. It will be the best laser engraver for small business. In comparison, the LaserPecker 4, which is usually around the same price, only features a 2W laser. Derfor, despite the approximately $500 price difference, the B4 laser’s 20W power significantly outperforms the LaserPecker, saving considerable time in the engraving process.

These insights stem from the speaker’s past experiences with various lasers, with the ComMarker B4 being deemed the best value for money currently available. I tillegg, as of recording the video, there are Black Friday sales ongoing, allowing viewers to purchase the laser at an even lower price using the provided discount code on the website. Links to the products mentioned are provided in the video description for easy access.

Concluding the video, the speaker invites viewers to leave any questions in the comments, promising to respond promptly. They express gratitude for watching and bid farewell, signaling the end of the video.

Once again, we appreciate Randy May’s willingness to develop and share on YouTube his experience with the Commarker B4 fiber laser graveringsmaskin. I’m hoping for another chance to work with Randy May in the future.
