Production guidance

This STAINLESS STEEL 304 - MOPA Color (Orange/Amber) metal record pairs 50% power with 600 mm/s on JPT M7 60W, using 1 pass, 70 kHz, 0.003 mm hatch spacing, and 150 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. Orange/amber color. Longer pulse width at moderate frequency. Source: hispeedlaser.com MOPA color chart (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. A 0.003 mm hatch is fine enough that overlap error shows: verify the galvo or gantry is square before running a large field.
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 (Orange/Amber) recipe is: “Orange/amber color. Longer pulse width at moderate frequency. Source: hispeedlaser.com MOPA color chart (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.
