On Startup, Machine crashing into end stops

Some machines will home automatically on startup without receiving a homing command. Yours obviously should not be doing that if it doesn’t have limit switches, so there could be a problem with its firmware. One thing to try is to connect to it and then enter $22=0 in the Console window in LightBurn. That should disable homing entirely in your laser’s firmware. If you’re worried about damaging your machine on startup, you can unplug the stepper motors first, so it can’t move.

If that doesn’t work, I recommend contacting Atomstack and looking into re-flashing your laser’s firmware.
