NEJE 3 Max with A40640 module (dual-beam, ~10–15W output). Community and product documentation confirm anodized aluminum as a supported surface engrave material. 4000 mm/min at 100% power is consistent with other 20–30W diode machines at this wattage class.

Baltic birch glue layers absorb energy unevenly. 3 passes needed. Check flatness of sheet before long runs.

Easy clean cut on cardboard. Skip air assist on cardboard — can cause flare-ups. Watch the cut closely.

Cork cuts in 2 passes at 11W. No air assist recommended — airflow can cause blowout in porous cork.

Cork chars easily — keep power low. Good for coasters and pot stands. Lovely contrast at 30%.

Good white engrave on black slate. Invert image. 80% power at this speed gives a consistent bright mark. Wipe surface with damp cloth after.

2–3mm veg-tan with 2 passes. Air assist helps edge quality. Watch for overheating on tight curves in fine shapes.

Good dark engrave on veg-tan leather. Start at 40% and dial up. Result varies with hide thickness — test on scrap.

MDF is tough for 11W — 4 passes needed. Air assist is critical to prevent MDF flare-ups and manage char.

Good fill engrave at 2500 mm/min. Bump to 60% for a darker mark. 254 DPI is the sweet spot for the 11W module.

11W module cuts 3mm basswood in 2 passes with air assist. NEJE 3 Max has a solid dual-rail frame which gives consistent results across the whole bed.

What settings should I use to cut 3mm Walnut Plywood on the NEJE 3 Max?

A community-tested starting point is speed 500 mm/min, power 100% in 2 passes. Always run a test cut on scrap to confirm before committing to your project.

Can the NEJE 3 Max engrave metal?

Diode lasers can mark anodized aluminium, coated metals, and powder-coated surfaces without any spray. For bare steel, brass, or copper you need a marking compound like Cermark or Dry Moly. Fiber lasers mark bare metal directly without any coating.
