About Birke Settings for the Generic CO2 40-60W

The Generic CO2 40-60W cuts Birke cleanly at 4.17 mm/s with 80% power over 3 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 Birke, 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.
