How to Set Up Rubber on the xTool S1 40W

1. 1Secure your rubber 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 rubber before committing to your final project piece. Adjust power up or down by 5–10% based on results.

What to Expect When Lasering Rubber

Cutting rubber produces a strong, unpleasant smell — robust ventilation or an enclosure with a fume extraction system is essential. Cut edges will be clean but may show slight melting. Engraving creates a lighter mark on dark rubber surfaces. Rubber stamp making is one of the most popular laser applications for this material. 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.
• ✗Not having proper ventilation — laser-cut rubber produces intense, noxious fumes that are harmful to breathe. A fume extraction system is essential, not optional.
• ✗Using rubber that contains chlorine (such as some synthetic rubbers) — these release hydrochloric acid fumes when lasered.

Tips for Rubber on Laser Machines

• ✓Use dedicated laser-safe stamp rubber (e.g., trodat or similar) for cleanest results.
• ✓Mirror your design before engraving stamps so the impression reads correctly.
• ✓Lower speed with multiple passes gives deeper, cleaner stamp impressions.
• ✓Clean rubber residue from the laser bed and lens after each session -- it can be sticky.
• ✓Air assist should be moderate -- too strong and it cools the rubber before cutting through.
