If the laser isn't cutting through cleanly, slow down or add a pass before pushing power higher — excessive power causes charring and wider kerfs. Air assist is highly recommended for wood and organic materials to clear smoke and protect the lens.
Once you find settings that work, save them in Laser Lab to build your personal settings library. The AI predictor uses your calibrated results to suggest starting points for new materials automatically — so the more you log, the smarter it gets.
For cutting Cotton Fabric on the Thunder Laser Nova/Bolt Series (80W CO2), start at 300 mm/s speed and 90% power. These are manufacturer-verified starting points — always test on scrap first.
Yes — air assist is recommended when cutting Cotton Fabric on the Thunder Laser Nova/Bolt Series (80W CO2). It clears smoke from the cut path, reduces charring, and protects your lens from debris.
The manufacturer recommends 1 pass to cut through Cotton Fabric at 300 mm/s and 90% power. If the cut isn't clean, try reducing speed slightly before adding more passes.
Incomplete cuts are usually caused by incorrect power, speed, or focus distance. If edges are charred, try increasing speed or reducing power. If the laser isn't cutting through, reduce speed or increase power — or add an extra pass. Also verify your focal distance is correct for the material thickness and that your lens is clean.
