Diode Laser Settings by Material
Every diode recipe in the Laser Data Library in one table: 6 starting values across wood, metal, acrylic and leather. Each row opens the free LightBurn test grid bracketed around its own power and speed, so the first burn on your machine checks the number instead of trusting it.

Diode Laser Settings by Material: every recipe
Each row opens the free LightBurn test grid with that row's values filled in. No account needed.
| Material | Machine | Power | Speed | Frequency | Hatch | Passes | Pulse | Evidence | Test grid |
|---|---|---|---|---|---|---|---|---|---|
| WOOD (Softwood/Pine) - Diode Engrave | Diode 450nm 10W | 65% | 120 mm/s | Default | 0.1 mm | 1 | — | Baseline | Make a test grid |
| WOOD (Hardwood/Oak) - Diode Engrave | Diode 450nm 20W | 70% | 100 mm/s | Default | 0.1 mm | 1 | — | Baseline | Make a test grid |
| LEATHER (Veg-Tan) - Diode Engrave | Diode 450nm 10W | 55% | 130 mm/s | Default | 0.08 mm | 1 | — | Baseline | Make a test grid |
| ACRYLIC (Dark/Black) - Diode Engrave | Diode 450nm 10W | 75% | 100 mm/s | Default | 0.1 mm | 1 | — | Baseline | Make a test grid |
| WOOD (Plywood 3mm) - Diode Cut | Diode 450nm 20W | 100% | 6 mm/s | Default | 0 mm | 3 | — | Baseline | Make a test grid |
| STAINLESS STEEL - Diode Anneal Mark | Diode 450nm 20W | 45% | 80 mm/s | Default | 0.08 mm | 1 | — | Baseline | Make a test grid |
Production guidance for Diode Laser Settings by Material
These rows come from the same records as the Parameters Library and the settings-by-material tables. All of them are bundled baselines with no vouch or proof-burn photo, recorded on the source and model shown in each row. Wattage, lens, focus and the material finish change the result more than the table can, so treat a row as the centre of a test, not a production preset.
- 1. Diode sources need slower speeds and more passes than fiber or CO2 for the same result, and a spot that is genuinely in focus matters more than raw wattage.
- 2. Grain direction, resin pockets and moisture content move the result more than the numbers do — run the test square on the same board you plan to cut, not a different piece of the same species.
- 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. Cast and extruded acrylic behave differently at the same settings — cast frosts white and extruded tends to melt, so confirm which sheet you have before trusting these numbers.
- 5. Change one value at a time. Burn the bracketed grid, pick the cleanest cell, then run a second, narrower grid around it before a customer part.
Source data reviewed 2026-08-09. The test grid link writes the row's power, speed, and any frequency, pulse width, hatch interval and pass count it records into the grid's Constant Values, then sweeps power from half to one and a half times the row's value across and speed the same way down. Burn it on matching scrap, keep the winning cell, and save it in the Parameters Library.
