How to Set Up Fabric on the Thunder Laser Nova 35 80W

1. 1Secure your fabric 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. 4Keep a fire extinguisher or spray bottle nearby. Fabric is flammable — never leave the machine unattended while cutting this material.
5. 5Enable air assist if available. A steady stream of air at the cut point removes debris, reduces charring, and helps prevent flare-ups.
6. 6Enter 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.
7. 7Run a small test cut or engrave on a scrap piece of fabric before committing to your final project piece. Adjust power up or down by 5–10% based on results.

What to Expect When Lasering Fabric

Laser-cut fabric edges are sealed by the heat, preventing fraying — this is one of the biggest advantages of laser cutting textiles. Expect slight darkening or browning on cut edges depending on the fabric type and color. Engraving creates a visible surface texture change or color shift. Synthetic fabrics may melt slightly at the edges. With 80W of CO2 power, this machine cuts thick acrylic, wood, and other non-metals rapidly — usually in a single pass — and holds up to high duty cycles for production runs. Edge quality stays excellent even at speed.

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.
• ✗Over-powering thin or delicate stock — at 80W it is easy to melt acrylic or scorch thin wood. Lower the power and raise the speed for fine work.
• ✗Leaving the machine unattended — lightweight fabrics are flammable and can ignite if the laser pauses or settings are too high.
• ✗Not weighing down or pinning the fabric flat — fabric that is not perfectly flat will produce uneven cuts and may shift during the job.

Tips for Fabric on Laser Machines

• ✓Pin or tape fabric taut to the bed to prevent movement and wrinkling.
• ✓Natural fibers (cotton, linen) cut cleanly while synthetics tend to melt.
• ✓Use low power and higher speed for delicate fabrics to avoid burning.
• ✓A honeycomb bed works best for fabric to allow airflow underneath.
• ✓Denim and canvas are the easiest fabrics to laser cut consistently.
