How to Set Up Birch Plywood on the Atomstack S40 Pro 36W

1. 1Secure your birch plywood flat on the work bed using clamps, magnets, or a honeycomb pin set to prevent movement during the job.
2. 2Set your focus distance accurately — use the auto-focus probe if your machine has one, or measure manually with the focus gauge.
3. 3Enable air assist if available. A steady stream of air at the cut point removes debris, reduces charring, and helps prevent flare-ups.
4. 4Enter the speed, power, and pass count from the settings table above into LightBurn. The table lists both mm/min and mm/s — LightBurn defaults to mm/s, so use the mm/s value unless you have switched units. Use the “Cut” or “Engrave” layer settings panel.
5. 5Run a small test cut or engrave on a scrap piece of birch plywood before committing to your final project piece. Adjust power up or down by 5–10% based on results.

What to Expect When Lasering Birch Plywood

Plywood cut edges will show charring that varies depending on the glue layers within the material. Some plywood brands produce heavier smoke due to adhesive content. Engravings appear as a dark brown contrast on the surface veneer. Multiple passes may be needed for thicker sheets due to inconsistent internal layers. With 36W on tap, this machine cuts thick stock fast — often in a single pass — which limits heat buildup and keeps edges cleaner than slower low-power machines. The trade-off is that fine engraving needs the power dialed well down to avoid over-burning.

Common Mistakes to Avoid

• ✗Running at full power on the first attempt — always start with a test piece at the recommended settings and adjust incrementally. Going straight to maximum power risks burning through the material or causing fire.
• ✗Running at full power out of habit — a 36W diode usually needs far less power than expected for engraving and thin cuts, and too much melts or burns the material.
• ✗Using cheap plywood with thick interior glue layers — these can cause inconsistent cuts where the laser fails to penetrate the adhesive. Use laser-grade plywood for best results.
• ✗Not testing each new batch of plywood — different brands and batches vary significantly in density and glue content.

Tips for Birch Plywood on Laser Machines

• ✓Choose laser-grade plywood when possible -- it uses less glue and cuts more cleanly.
• ✓Glue layers may require extra passes or slightly higher power.
• ✓Birch plywood engraves with good contrast due to its light color.
• ✓Warped sheets will produce inconsistent cuts -- always check flatness.
• ✓Masking tape both sides to prevent smoke staining on surfaces.
