About Birch Wood Settings for the Boss Laser LS-1420 100W

The Boss Laser LS-1420 100W cuts Birch Wood cleanly at 15 mm/s with 70% 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 Birch Wood, 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.
