I have a new Printrbot Simple Metal which uses an inductive proximity switch for the Z axis position. The prox. works fine as the software will allow me to home z in multiple locations on the bed when I do so through the manual controls.
While I am completely familiar with cnc controls this is my first 3d printer.
When I go into bed leveling it homes xyz as it should, just as it does when I press "home all" in jog mode, but when the machine moves to the the y stops where it should and the z axis comes down until it crashes into the bed even though the switch was made way before it did so.
I'm sure I am missing some parameter but I was up until 1am reading and I can't find it.
Thanks in advance!
