The ComMarker ComMarker B6 60W MOPA cuts Knife (Stainless Steel) cleanly at 200 mm/s with 85% 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 Knife (Stainless Steel), 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.

Air assist is strongly recommended when cutting Knife (Stainless Steel). It clears smoke from the cut path, reduces charring, and helps protect your laser lens.
The manufacturer recommends 1 pass to cut through Knife (Stainless Steel) at 200 mm/s and 85% 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.
