My 0,0,0 origin is exactly where I want it to be. As soon as I hit print the head moves to the center on the plate and jerks a 1/4" up and then starts printing. Any one have any clue why the Z axis would change position? It was not doing that before. Thank you in advance for any advice.
I had a similar, but not identical, issue. For me, auto bed leveling was #defined in configuration.h, causing the homing command to operate differently.
Does 0,0,0 work only when you home each axis individually or when you home all at once?
