Glue-layer banding is normal. Masking tape tip for photo engrave. 3 independent sources.

10W cut: 100% · 300 mm/min · 2 passes · engrave: 45% · 2,000 mm/min
Apply masking tape before cutting — prevents delamination

10W cut: 100% · 250 mm/min · 2–3 passes · engrave: 50% · 3,500 mm/min
More resin than basswood → more smoke + flare risk. Air assist essential.

10W engrave: 65% · 2,800 mm/min · 300 DPI · 1 pass
Dark wood = limited contrast. Use white paint infill for readable results.

10W engrave: 62–70% · 2,500–3,000 mm/min · 1 pass
3mm cut: 800 mm/min · 2 passes. Fine grain, warm contrast, fewer passes than maple.

10W engrave: 75–85% · 2,500–4,000 mm/min · 1 pass
3mm cut: 5–6 passes. Pale wood = highest contrast. Best for cutting boards & awards.

10W engrave: 70% · 2,500 mm/min · 300 DPI · 2 sources agree
Open-grain pore texture is the signature look. Cutting at 10W is hard; 20W recommended.

20W engrave: 48% · 3,500 mm/min · 1 pass
Cut 3mm: 72% · 1,000 mm/min · 2 passes. Aromatic oils, use masking tape to reduce smoke staining.

20W engrave: 65% · 2,800 mm/min · 1 pass
Cut 3mm: 97% · 800 mm/min · 2 passes. Fine grain, guitar-body wood, denser than basswood.

20W: 75% · 3,500 mm/min · 1 pass
Fire risk: never leave unattended

40W: 37% · 6,000 mm/min · 1 pass · no air assist
Coasters, trivets, tiles — cork chars easily, start conservative

20W 160gsm: 35–45% · 5,000–7,000 mm/min · 1 pass
Key rule: faster is cleaner — slow speed chars paper edges. Air assist off for light paper.

40W: 75% · 3,500 mm/min · 300 DPI · 1 pass · PVC-free rubber only
Flip design horizontally first or the stamp prints backwards

10W: 80% · 600 mm/min · 1 pass · no air assist
Dark foam only — white EVA reflects the 450 nm beam. Confirm EVA, not PVC.

20W quilting cotton: 90% · 238 mm/s · 1 pass · max air assist
20W craft felt 3mm: 80% · 700 mm/min · no air assist. PVC check required.

Indigo bleaching effect — no coating needed
20W: 22–45% · 5,000–5,500 mm/min · 254 DPI · 1 pass

Opaque/colored cast only — clear is transparent to 450nm
20W: 95% · 800 mm/min · 3 passes

Opaque, two-tone & frosted — surface ablation, not cutting
10W: 40% · 4,000 mm/min · air assist off. Two-tone removes colour coat for signs.

Veg-tan only — chrome-tanned releases Cr VI carcinogen
20W: 22% · 4,000 mm/min · 1 pass

40W: 100% · 900 mm/min · 1 pass · air assist required
Veg-tan only. 10W: 85% · 1,400 mm/min · 2 passes

Ablates anodized layer — bare metal needs marking spray
20W: 30% · 4,500 mm/min · 1 pass

Marking spray required — bare steel reflects 450nm
10W: 70% · 800 mm/min · 1 pass · Cermark or moly-lube

No spray needed — laser ablates coating directly
10W: 90% · 2,000 mm/min · 1 pass · tumblers need rotary
