|---|---|---|---|---|---|---|
| engrave | — | 1000 | 90% | 512 | — | 3D slice-mode relief engraving; alternate parameter set vs the B4 60W MOPA 3D relief pass listed above (different frequency/pulse width for same 512-pass job). |
The ComMarker ComMarker B6 60W MOPA cuts Coin (Brass) cleanly at 1000 mm/s with 90% power over 512 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 Coin (Brass), 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 Coin (Brass) on the ComMarker ComMarker B6 60W MOPA, start at 1000 mm/s speed and 90% power with 512 passes. These are manufacturer-verified starting points — always test on scrap first.
Air assist is strongly recommended when cutting Coin (Brass). It clears smoke from the cut path, reduces charring, and helps protect your laser lens.
The manufacturer recommends 512 passes to cut through Coin (Brass) at 1000 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.
