I had to reconfigure my computer after a virus made the computer crash the other day. Anyway, I got just about everything working right except for the homing switches. The z will move until the home switch is activated (when the LED lights up for M3 Home in diagnostics) then it stops and sets zero as that point. The x and y both move until their home switch is activated (LED lights up for M1 and M2home) but then they don't stop! The motor just keeps trying to turn and rams the table up against the column (the y axis). In the homing/limits tab I have home neg checked for x and y but not for z. Auto zero is checked for all 3. In ports and pins active low is checked for x home, y home, and z home under input signals. Any help?
I just had this issue setting up homing for the first time. check that your inputs are active, on the correct port ( which was not the case for me) and the correct pin. See if that helps.
