The Thunder Laser Nova 35 cuts Plexiglas cleanly at 10 mm/s with 80% power. Always test on a scrap piece first — every machine is slightly different, and variables like tube age, lens condition, and material batch can shift results.
For Plexiglas, the key variables to dial in are speed and power. 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 Plexiglas on the Thunder Laser Nova 35, start at 10 mm/s speed and 80% power. These are manufacturer-verified starting points — always test on scrap first.
Air assist is not required for Plexiglas on the Thunder Laser Nova 35 according to manufacturer data, though it can still help reduce smoke and improve cut quality on organic materials.
The manufacturer recommends 1 pass to cut through Plexiglas at 10 mm/s and 80% 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.
