Okay I was wrong, the firmware is the same but still both machines are somewhat sick, depending on how it's wired, it is either x or y that reacts to the triggered z probe, if it's y it's no big deal since i am doing quick homing, the probe is quickly off the bed and when y homes it is no more triggered. Question, I am trying to add home all into the firmware G29, but cant figure out how, any suggestions?
