Production guidance

This BRASS - White Mark metal record pairs 100% power with 2000 mm/s on Raycus 30W, using 4 passes, 60 kHz, 0.03 mm hatch spacing, and no recorded pulse-width override. Compare every listed field with the source, lens, focus method, and material finish on your machine before transferring the recipe.

1. 1. High contrast white color on brass.
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. Run all 4 passes without re-homing between them — re-registering mid-job is the usual cause of a doubled or ghosted edge.
6. 6. Record the successful result in the Parameters Library so the next production run is repeatable.

The bundled note for this BRASS - White Mark recipe is: “High contrast white color on brass.” 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.
