Best Laser Settings for Engraving Wood (A Practical Guide)
The best laser settings for engraving wood balance power, speed, and resolution (DPI or line interval): lower power and higher speed give a light, crisp engrave, while higher power and lower speed burn darker and deeper. Exact numbers depend on your laser's wattage and the wood, so the reliable method is to start from sensible ranges and run a quick test grid on scrap of the same material.
The three settings that matter
Power is how hard the laser fires — more power burns darker and deeper. Speed is how fast the head moves — faster means less burn per spot. DPI (or line interval) is how densely the scan lines pack — higher DPI gives finer detail but more total burn and slower jobs. These three trade off against each other; changing one usually means adjusting another.
Where to start by laser type
These are starting points to test, not final numbers. Diode (5-20W): high speed, moderate power, 254-318 DPI — diodes engrave wood beautifully. CO2 (40-60W): higher speed, lower power percentage because CO2 is much hotter, 300 DPI. Always cut your real numbers in by testing, because a 5W diode and a 60W CO2 reaching "the same darkness" use very different settings.
Run a test grid first
The fastest way to dial in any material is a test grid: a small array of squares where power increases along one axis and speed along the other. Engrave it on scrap of the exact wood you will use, then pick the square that looks right. Ten minutes of testing saves a ruined workpiece.
Wood matters as much as settings
Hardwoods (maple, cherry, walnut) engrave with clean contrast. Softwoods and plywood have uneven grain and glue layers that burn inconsistently. Lighter woods show more contrast than dark ones. Masking tape over the surface reduces smoke staining on light woods. The same settings can look great on maple and muddy on pine.

What power and speed should I use to engrave wood?
It depends on your laser's wattage and the wood. As a starting point: diodes use moderate power and high speed; CO2 uses lower power percentage and higher speed because it runs hotter. Always confirm with a test grid on scrap.
What DPI is best for engraving wood?
Around 254-318 DPI is a good balance of detail and speed for most wood. Higher DPI adds detail but burns more and runs slower; lower DPI is faster but coarser.
Why is my wood engraving coming out blotchy?
Usually the wood, not the settings — plywood glue layers and uneven grain burn inconsistently. Try a solid hardwood like maple or cherry, and run a test grid for that specific board.
How do I get a photo to engrave well on wood?
Use a grayscale image prepared for engraving (good contrast, the right resolution for your DPI). See our guide on preparing a photo for laser engraving.
