Frequently asked questions
What speed should I use to engrave Slate on the Atomstack X20 Pro?
The top-rated community setting uses 4000 mm/min at 55% power. Community-tested on 20W diode lasers via LA Hobby Guy (lahobbyguy.com/bb/viewtopic.php?t=2916 'Settings for Slate'). Multiple users with 20W machines (including Atomstack X20 Pro) report 4000mm/min at 55% power as a reliable starting point. Lower power + faster speed consistently yields cleaner, lighter contrast. Wiping slate with acetone before engraving improves results. No clear coat needed post-engrave.
