Production guidance

This POWDER COAT - Engrave/Ablate coated record pairs 34% power with 750 mm/s on Fiber 20W, using 1 pass, 25 kHz, 0.025 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. Ablates powder coat to reveal bare metal underneath.
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. Coating thickness is the real variable. Apply evenly, let it cure fully, and re-test whenever you change spray batch or application method.
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. Change one variable at a time — power, then speed, then frequency — so you can attribute the improvement when you find it.
6. 6. Record the successful result in the Parameters Library so the next production run is repeatable.

The bundled note for this POWDER COAT - Engrave/Ablate recipe is: “Ablates powder coat to reveal bare metal underneath.” 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.
