Production guidance

This STAINLESS STEEL 304 - MOPA Color (Black, LIPSS) metal record pairs 55% power with 300 mm/s on JPT M6/M7 30W, using 2 passes, 1500 kHz, 0.005 mm hatch spacing, and 2 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 black via LIPSS nanostructuring. Very high freq + ultra-short pulse. X-hatch essential. Source: JPT MOPA application note (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. 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 304 - MOPA Color (Black, LIPSS) recipe is: “Deep black via LIPSS nanostructuring. Very high freq + ultra-short pulse. X-hatch essential. Source: JPT MOPA application note (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.
