Commarker B6 30W — Stainless Steel

Deep material removal / mechanical engraving. Low frequency is more aggressive. Multiple passes with slight defocus between passes can clear debris. LightBurn forum 30W settings thread. | Freq: 25kHz, pulse: 200ns, line interval: 0.03mm

BCF/JPT 30W validated settings from barchlaser.com 150mm lens test. Same core parameters as 20W B4 but 30W gives slightly faster throughput. Dark oxide mark. LightBurn: set freq min 20, max 200. | Freq: 30kHz, pulse: 200ns, line interval: 0.01mm

Fast surface mark for high-volume batch jobs — dog tags, name badges, tool marking. 55% at 4000mm/min gives a grey mark rather than deep black. Use deep black settings (80% at 2000) for items that will be handled heavily.

Deep black oxide mark on brushed stainless. Fiber laser oxidises the surface rather than removing material — the result is permanent and survives dishwashing. At 30W you can push speed higher than 20W machines while maintaining full mark depth.
