Commarker B6 30W

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

Annealing color varies by exact frequency and power. 30W produces vivid colors well. Same anneal parameters as stainless but titanium responds faster — run test tile. Based on omglaser.com titanium note + LightBurn MOPA color speed thread. | Freq: 100kHz, pulse: 20ns, line interval: 0.02mm

Copper reflectivity at 1064nm makes marking difficult at 30W. Longer pulse width + multiple passes recommended. Full watt output, slow speed. Still marginal — 50W+ is the community consensus for reliable copper engraving. Based on omglaser.com 60W copper settings scaled proportionally. | Freq: 30kHz, pulse: 500ns, line interval: 0.02mm

30W gives noticeably better results than 20W on brass. Multi-pass at 0°/45°/90° crosshatch per omglaser.com brass coin data (60W scaled to 30W). No air assist to avoid yellowing/tarnish. | Freq: 45kHz, pulse: 200ns, line interval: 0.04mm

Creates bright white/silver mark on black anodize. Short ns pulse critical. Same approach as general anodized Al but maximise power to ensure full coat ablation in one pass. LightBurn material library listings for B6 30W confirm this range. | Freq: 55kHz, pulse: 4ns, line interval: 0.04mm

White mark result on colored anodize. Short pulse (4 ns) + high frequency prevents burning. 30W reference from barchlaser.com MOPA aluminum + white aluminum setting (100% / 2000mm/s / 55kHz) adapted for mark-not-cut. | Freq: 55kHz, pulse: 4ns, line interval: 0.05mm

30W gives a good clean dark mark on tumblers in a single pass. Rotary required. Higher speed than flat work due to consistent cylindrical surface. Derived from gweike cloud tumbler guide + LightBurn 30W anneal settings (speed 1500, 80%, 50kHz for heavy anneal — lightened for tumbler use). | Freq: 50kHz, pulse: 200ns, line interval: 0.05mm

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

Chrome plating is hard to mark cleanly — the laser marks the chrome layer itself rather than the steel underneath. Result is a subtle contrasting mark. Multiple passes can remove the chrome entirely which gives a different aesthetic. Test on hidden area first.

Deep dark mark on carbon steel — great for tool marking, knife blades, and industrial parts. The result is rust-resistant when the oxide layer forms properly. Wipe with a dry cloth after marking to remove debris.

Sterling silver marks with a dark oxidised surface. Test power carefully — fine jewellery pieces need lower power to avoid overheating thin sections. At 40% you get a clear mark without distorting thin wire settings.

Removes powder coat cleanly in one pass. Use a rotary attachment and the correct wrap template for your tumbler size. The 30W machine is fast enough for production batch runs. Clean the tumbler surface with isopropyl alcohol before marking.

Very gentle settings on gold-filled pieces — too much power damages the gold layer. Test on a scrap or hidden area first. At 35% you get a subtle surface mark. Solid gold can handle 45-50% safely.

Copper is reflective and challenging for fiber lasers. Use high power and be cautious — a 30W machine can mark copper well but test your power carefully. The mark will be a dark oxidation. Polished copper may need multiple passes.

Colour marking on titanium — the colour changes with speed. At 1200mm/min you get warm gold tones. Slow down to 800mm/min for deeper blue/purple. Speed affects colour more than power on titanium. Always test on a scrap piece first.

Dark oxide mark on raw brass. Works well for trophies, plaques, and jewellery findings. Polished brass needs slightly higher power than brushed. Rinse after engraving to remove any residue.

Removes anodising to reveal bright bare aluminium. Exceptionally fast on anodised aluminium — the contrast is excellent on coloured anodised blanks. Works on all colours. Great for dog tags, tumblers, and phone cases.

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.

What materials can the Commarker B6 30W engrave or cut?

The Commarker B6 30W has community-tested settings for Coated / Powder Coated Steel, Titanium, Copper, Brass, Black Anodized Aluminum, Anodized Aluminum, Stainless Steel Tumbler, Stainless Steel, and 5 more. Results vary by material batch, focus, and ambient conditions — always test on scrap first.

Is the Commarker B6 30W compatible with LightBurn?

Yes, the Commarker B6 30W works natively with LightBurn.

Can the Commarker B6 30W mark bare metal without any coating?

Yes. Fiber lasers mark stainless steel, brass, copper, titanium, and anodized aluminium directly — no Cermark or marking spray needed. This is the main advantage of fiber over CO₂ or diode machines for metal personalisation.
