Production guidance

This STAINLESS STEEL (UV) - Black Mark metal record pairs 100% power with 500 mm/s on UV 5W, using 2 passes, 130 kHz, 0.025 mm hatch spacing, and 1 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. Ultra-fine mark using UV laser. Cold marking process.
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. UV marks cold, so contrast comes from surface chemistry rather than heat. Focus tolerance is tight; a fraction of a millimetre off will wash the mark out.
5. 5. Run all 2 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 STAINLESS STEEL (UV) - Black Mark recipe is: “Ultra-fine mark using UV laser. Cold marking process.” 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.
