How to Set Up Rubber on the Glowforge Pro

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. 3Ensure your water cooling system is running and the coolant temperature is between 15–25°C before starting the laser.
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 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.

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.
• ✗Forgetting to check the water cooling system before starting. CO2 laser tubes can overheat and suffer permanent damage if the coolant is not flowing or is above 25°C.
• ✗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.
