About Leather - Nubuck Black Settings for the WeCreat Lumos Ultra UV 5W

The WeCreat Lumos Ultra UV 5W cuts Leather - Nubuck Black cleanly at 20 mm/s with 100% 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 Leather - Nubuck Black, 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.
