How to Set Up Cork on the xTool S1 40W

1. 1Secure your cork 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. 3Keep a fire extinguisher or spray bottle nearby. Cork is flammable — never leave the machine unattended while cutting this material.
4. 4Enable air assist if available. A steady stream of air at the cut point removes debris, reduces charring, and helps prevent flare-ups.
5. 5Enter 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.
6. 6Run a small test cut or engrave on a scrap piece of cork before committing to your final project piece. Adjust power up or down by 5–10% based on results.

What to Expect When Lasering Cork

Cork cuts very cleanly with a laser, producing minimal charring compared to wood. The natural brown edge color blends well with the cork surface. Engravings appear as a darker shade against the natural cork. Expect a mild, pleasant woody smell during cutting. Cork is one of the easiest materials to laser due to its low density and consistent composition. With 40W 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 40W diode usually needs far less power than expected for engraving and thin cuts, and too much melts or burns the material.
• ✗Using too much power, which can cause cork to burn through or ignite. Cork is low-density and cuts easily — start with conservative settings.
• ✗Skipping the focus calibration step — an out-of-focus beam produces wider, less precise cuts and weaker engravings. Re-check focus every time you change material thickness.

Tips for Cork on Laser Machines

• ✓Cork engraves with excellent contrast -- even low power produces visible marks.
• ✓Use light air assist to prevent scorching without blowing lightweight cork pieces.
• ✓Thin cork sheets (under 3mm) are easiest to work with for beginners.
• ✓Apply masking tape to reduce smoke staining around engraved areas.
• ✓Cork coasters are one of the fastest-selling laser craft products at markets.
