Frequently asked questions
What speed should I use to engrave Anodized Aluminum on the Atomstack X20 Pro?
The top-rated community setting uses 4000 mm/min at 55% power. Community-sourced from LA Hobby Guy / LightBurn forum discussions. Atomstack X20 Pro user reported 4000mm/min at 55% power giving good results on anodized aluminum — low power + fast speed gives cleaner marks vs. high power + slow speed which digs in and looks rough. Source: diode laser community consensus at lahobbyguy.com/bb/viewtopic.php?t=33 and forum.lightburnsoftware.com/t/diode-laser-speed-and-power-guide/43192. Diode lasers ablate the anodized coating only; they do not mark bare aluminum.
Can the Atomstack X20 Pro cut Anodized Aluminum?
A 20W diode laser can mark or engrave metal surfaces but cannot cut through them — metal cutting requires a much higher-powered laser or a plasma cutter.
How many passes does the Atomstack X20 Pro need to engrave Anodized Aluminum?
All settings here use a single pass. Confirm focus and do a small test burn before committing to your final design.
Do I need air assist for Anodized Aluminum on the Atomstack X20 Pro?
Air assist is not flagged as required for these settings, but it is good practice during cutting operations to keep the lens clean and reduce char buildup.
