How to Set Up Cork on the Atomstack S40 Pro 36W

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. 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.

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.
• ✗Not accounting for the slower cutting speed of diode lasers compared to CO2. Diode lasers need multiple passes for thicker materials — be patient and let the machine do multiple passes rather than increasing power beyond recommended levels.
• ✗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.
