The Ortur LM2 Pro 20W cuts Pine Board cleanly at 1.67 mm/s with 100% power over 2 passes. 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 Pine Board, 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 Pine Board on the Ortur LM2 Pro 20W, start at 1.67 mm/s speed and 100% power with 2 passes. These are manufacturer-verified starting points — always test on scrap first.
Air assist is not required for Pine Board on the Ortur LM2 Pro 20W according to manufacturer data, though it can still help reduce smoke and improve cut quality on organic materials.
The manufacturer recommends 2 passes to cut through Pine Board at 1.67 mm/s and 100% 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.
