Why My Laser Engraving Looks Blurry

Understanding the Basics of Clear, Crisp Laser Engraving

If you’ve ever wondered, “Why does my laser engraver suddenly produce blurry or uneven results?」 — you’re not alone. Whether you’re using a beginner-friendly diode engraver or a high-precision system like the コムマーカーオムニ 1 また タイタン 1, blurry engraving usually points to a fixable issue—not a faulty machine.

レーザー彫刻機 works by focusing a beam of light onto the surface of a material to vaporize or ablate it with precision. But when something is off—focus, スピード, optics, or the material itself—that crisp precision turns into fuzzy lines, 焼けた端, or faded text.

Let’s break down the seven most common causes of blurry laser engraving and how to troubleshoot them.


上 7 Causes of Blurry Laser Engraving (and How to Fix Them)

1. Out-of-Focus Laser Beam

の #1 culprit. If your laser isn’t perfectly focused, the beam spreads wider than intended, leaving a blurry or charred mark.

  • Symptoms: Wide or soft lines, low contrast, scorched edges
  • 解決: Refocus the laser to the correct focal distance.
    • For ComMarker machines, this is easily done via electric autofocus or a manual gauge.
    • Use a ramp test to find the sharpest point (especially helpful if you’re unsure of the factory focus spacer).

2. Dirty or Fogged Lens

ほこり, 煙, and oil can build up on your lens—even with enclosed machines like the オムニ 1. A dirty lens scatters the beam and reduces engraving accuracy.

  • Symptoms: Faded marks, heat spots, inconsistent lines
  • Fix:
    • Use a microfiber cloth with isopropyl alcohol
    • Clean the lens and mirrors every 10–20 hours of use
    • Replace scratched or discolored lenses

3. Wrong Speed or Power Settings

Balance is everything. Too fast? You’ll get shallow engravings. 遅すぎる? You risk overburn and blurred details.

  • Quick Fixes:
    • Run a LightBurn Material Test Grid to dial in the best settings
    • For wood: Start with 600 mm/s @ 30% 力
    • For acrylic: Try 500 mm/s @ 35–50% power
    • For metal: Use a ファイバーレーザー like Titan 1 with pulse-width control for best clarity

4. Material Movement or Shift

If your material wiggles mid-job, you’ll get ghosting or double images.

  • Common Causes:
    • Loose clamps, inadequate jigs, air assist turbulence
  • Solutions:
    • Use strong magnets, corner brackets, or a honeycomb bed
    • For mugs, タンブラー, and curved objects, use a ロータリーアタッチメント like ComMarker’s 360° fixture

5. Loose Belts, Rails, or Mounts

Even a slight mechanical wobble causes misalignment—especially during fine raster engravings.

  • チェック:
    • X and Y axis belts (should feel taut, not floppy)
    • Linear rails (clean with dry brush and re-lube monthly)
  • Fix: Follow your engraver’s maintenance guide or contact ComMarker support for service tips.

6. Vibration from Table or Nearby Devices

You wouldn’t engrave on a trampoline—so don’t put your laser on a wobbly desk. Even a nearby 3D printer or fan can introduce vibration.

  • Fix:
    • Place your laser on a 頑丈, heavy table
    • 追加 anti-vibration feet or foam dampeners
    • Avoid placing engraver near heavy foot traffic or machinery

7. Low-Resolution Artwork or Software Errors

Not all files are created equal. A low-res PNG will never look as sharp as a properly prepped vector or 600 DPI bitmap.

  • Optimize Your Files:
    • Use SVG or AI for text and logos
    • Convert images to grayscale with high contrast
    • Set DPI between 300–600 in LightBurn or EZCad
    • Avoid using images with less than 72 DPI—they’ll always look pixelated

Diagnosing Laser Engraving Problems by Symptom

SymptomLikely Cause
Burned or soft edgesOut of focus, slow speed, or overpowered
Double linesLoose belts or unstable material
Weak engravingDirty lens or incorrect height
Wavy linesTable vibration or belt slippage
Misaligned designFile issue or material shifting mid-job

Pro Tips for Sharp Laser Engraving

  • Run test grids every time you switch materials
  • Refocus when engraving thicker items or switching substrates
  • Clean optics and rails every 10–20 hours
  • Save settings per material (LightBurn libraries make this easy)
  • Use jigs to align repeat jobs and batch runs

ComMarker Users: Easy Clarity Wins

  • オムニ 1 紫外線: Use ZeroBurn™ mode for crisp lines on plastics and glass
  • タイタン 1 ファイバ: Set pulse width for darker blacks or color variations
  • Use LightBurn’s Focus Tool to visualize and correct off-focus areas before engraving

よくある質問: Blurry Laser Engraving Troubleshooting

Q: My engraving is blurry only on one side. なぜ?
→ Your gantry might be misaligned, or your table isn’t level. Check both with a spirit level or calibration square.

Q: Can engraving get blurry even if my preview looks sharp?
→ Yes! The beam and motion system are physical—what you see on screen doesn’t always match if your machine isn’t clean or calibrated.

Q: Do I need to recalibrate focus for different materials?
→ Absolutely. Even 1mm of height difference can throw off your focus point.

Q: Is LightBurn better for solving clarity issues?
→ Yes. LightBurn gives you full control of speed, 力, DPI, and even beam overlap, helping you fine-tune precision.
