Production guidance

This ALUMINUM - Fiber Deep Engrave (30W) metal record pairs 100% power with 600 mm/s on Raycus 30W, using 10 passes, 20 kHz, 0.02 mm hatch spacing, and 200 ns pulse width. Compare every listed field with the source, lens, focus method, and material finish on your machine before transferring the recipe.

1. 1. Deep engrave on aluminum. Clean debris between passes. Source: rmlaser.us fiber aluminum parameters (2024).
2. 2. Treat this as an unverified baseline, not a production preset. A VERIFIED Parameters Library record requires three independent community vouches; an attached proof-burn image provides additional evidence.
3. 3. Bare metal is unforgiving of focus error: re-zero on the actual work surface rather than the bed, and wipe oils off before marking or the mark will read blotchy.
4. 4. MOPA pulse width is the parameter doing the work here — if the result drifts, adjust pulse width before touching power or speed.
5. 5. This is a 10-pass recipe, so cumulative heat is the risk: let the part cool between runs or the later passes will widen the mark.
6. 6. Record the successful result in the Parameters Library so the next production run is repeatable.

The bundled note for this ALUMINUM - Fiber Deep Engrave (30W) recipe is: “Deep engrave on aluminum. Clean debris between passes. Source: rmlaser.us fiber aluminum parameters (2024).” The source data was reviewed 2026-08-09; no independent vouch or proof-burn image is attached. Label the scrap test with the adjusted values and keep the accepted result with the production job.
