Coated / Powder Coated Steel

Powder coat is easier to ablate than bare metal. 2W can remove coating to expose steel, but results depend heavily on coating thickness and color. Thin coatings work in 1–2 passes; thick industrial coats may need more. xTool LightBurn forum painted tumbler data used as reference. | Freq: 40kHz, line interval: 0.05mm

Extra 10W over B4 means coating ablation is cleaner and faster. Slight speed increase vs 20W. Slight defocus +2mm on curved items. ComMarker B6 60W blog material settings + LightBurn painted tumbler thread (scaled for 30W). | Freq: 40kHz, pulse: 100ns, line interval: 0.05mm

Removes powder coat to expose bare steel underneath. Slightly defocus (+2mm) for cleaner coating ablation on curved objects. Consistent results across most powder coat brands. Based on LightBurn forum painted tumbler thread and general MOPA coated metal guidance. | Freq: 40kHz, pulse: 100ns, line interval: 0.05mm
