Andrew , have looked at pins.h board 33 but dont know how to do what you suggest . . edit pins.h to pus the Y endstop on the x-max pin, and plug Y into x-max. Ooooohh my head hurts. Can you explain the procedure it a little more ? I'm at a standstill now; just cant get the pronterface to control the rostock thru the ramps
