Find the problem by what you see, or look up the alarm or message shown on the screen or in the software. Each group opens on its own page.
The laser cuts weakly, emits no light, has a stopped fan, overheats, or produces faint engraving.
Lines shake, patterns deform, homing fails, motion stutters, sizes are wrong, axes stick or make noise, engraving is rough, or the frame is hit.
The machine stops, will not power on, shows a red light alarm, fails to connect or engrave from the app, stutters in LaserGRBL, or cannot read a TF card.
Cut edges discolor, flame detection fails or gives false alarms, the rotary mirrors patterns or does not work, or plastic parts are damaged.
Look up the exact text you see. The alarm numbers appear in AtomStack Studio, LightBurn and other GRBL software.
