Glowforge Basic Settings for Rubber
Recommended speed, power, and pass settings for rubber on the Glowforge Basic (40W CO2 laser, 10.6\u03bcm wavelength, 495\u00d7279mm work area). The Glowforge Basic is a beginner-friendly cloud-based CO2 laser with a simple drag-and-drop interface, ideal for makers new to laser cutting.
The Glowforge Basic is a 40W CO2 laser with a 495\u00d7279mm work area. Laser cutting rubber produces strong fumes that require robust ventilation. It is commonly used for making custom stamps. Below you will find tested starting parameters for cutting and engraving rubber on this machine.

How to Set Up Rubber on the Glowforge Basic
- 1Secure your rubber flat on the work bed using clamps, magnets, or a honeycomb pin set to prevent movement during the job.
- 2Set your focus distance accurately — use the auto-focus probe if your machine has one, or measure manually with the focus gauge.
- 3Ensure your water cooling system is running and the coolant temperature is between 15–25°C before starting the laser.
- 4Enable air assist if available. A steady stream of air at the cut point removes debris, reduces charring, and helps prevent flare-ups.
- 5Enter the speed, power, and pass count from the settings table above into LightBurn. Use the “Cut” or “Engrave” layer settings panel.
- 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.
