Setting Converter
Take a setting made for one laser and estimate a starting point for another wattage of the same laser type. Cross-type (diode ↔ CO2 ↔ fiber) isn’t converted — the wavelengths behave too differently.

Pick a brand + model to auto-fill laser type and wattage, or set them by hand.

Lower power, slower pass — less heat and charring on delicate materials.
These are math-based starting points (matched energy per pass), not guaranteed settings. Always test on scrap — real results depend on material, focus, lens, and air assist. For cutting, favor the faster option; for dark engraving on wood/MDF you may need to stay slower.
