The ComMarker ComMarker B4 20W cuts Tumbler (Stainless Steel) cleanly at 750 mm/s with 60% 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 Tumbler (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.

For cutting Tumbler (Stainless Steel) on the ComMarker ComMarker B4 20W, start at 750 mm/s speed and 60% power with 2 passes. These are manufacturer-verified starting points — always test on scrap first.
Air assist is strongly recommended when cutting Tumbler (Stainless Steel). It clears smoke from the cut path, reduces charring, and helps protect your laser lens.
The manufacturer recommends 2 passes to cut through Tumbler (Stainless Steel) at 750 mm/s and 60% 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.
