Production guidance

This GOLD - Deep Mark (20W) metal record pairs 68% power with 2500 mm/s on Fiber 20W, using 1 pass, 190 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. Deeper mark on gold. Higher speed with high frequency.
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. 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 GOLD - Deep Mark (20W) recipe is: “Deeper mark on gold. Higher speed with high frequency.” 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.
