OLM3 Getting Error -> ALARM:2 G-code motion target exceeds machine travel

Enable “Out of bounds warning” in Edit->Device Settings.

That may warn you before you get into this situation.

You should never get this alarm if you follow these conditions:

  1. You home the machine before each session
  2. You use jogging controls exclusively. Do not move the laser head by hand after homing.
  3. You don’t ignore any warnings

Additionally, using Absolute Coords as your Start From mode makes this much simpler.
