These 2 settings cover cut and engrave Leather on the K40 CO2 (35W CO₂ laser). Genuine leather tolerates lower power than faux leather; go slowly and increase passes rather than power to avoid scorching. Some settings use multiple passes for a cleaner cut: pin or tape your material flat before running to prevent shift between passes.
