Step 1: Choosing the Right Wood

Not all wood engraves equally. The best types include:

Best Woods for Laser Engraving

Avoid:

• Resinous woods (pine, cedar) – Can create uneven burns

• Treated/painted wood – Releases toxic fumes

Step 2: Preparing Your Design

Software Options

• LightBurn (Best for advanced users)

• RDWorks (Common with Chinese lasers)

• Inkscape (Free for vector designs)

Design Tips

✅ Use high-contrast black & white images for best results
✅ For photos, apply a stipple or dithering effect
✅ Test small sections first with different power settings

Step 3: Setting Up the Laser

Optimal Engraving Settings (CO2 Laser 40W-100W)

Note:

• Higher DPI = Finer detail (but slower engraving)

• Lower speed + higher power = Deeper engraving

Focusing the Laser

1. Use the manual focus tool (if available)

2. Perform a ramp test to find the ideal focal distance

3. Ensure the lens is clean for sharp engraving

Step 4: Running the Engraving Job

1. Secure the wood (use masking tape or weights to prevent shifting)

2. Turn on air assist (reduces scorching)

3. Start with a low-power test run (prevents overburning)

4. Monitor the engraving for consistency

Step 5: Post-Processing for a Professional Finish

Cleaning the Engraved Wood

• Remove soot with a soft brush or damp cloth

• Sand lightly (if needed) for a smoother finish

Enhancing Contrast

• Stain or oil (darkens engraved areas)

• Paint fill (for colored effects)
