Production guidance

This SLATE - Photo Raster other record pairs 10% power with 300 mm/s on Fiber 50W, using 1 pass, 45 kHz, 0.02 mm hatch spacing, and 400 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. Excellent for photo engraving on natural slate.
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. Unlisted substrates vary batch to batch. Treat these numbers as a starting point and step power in small increments rather than jumping to the listed value.
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 0.02 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 SLATE - Photo Raster recipe is: “Excellent for photo engraving on natural slate.” 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.
