General Mach Discussion / Homing and limits don't work right
« on: February 27, 2009, 07:47:14 PM »
Hello,
I have my limit switches and home switches wired into one pin per axis, so that one limit switch will share duty as a home switch as described in the mach 3 install and config pdf. I only have X,Y, and Z axes. When I do a ref all, my axis will move in the right direction, but when it hits the switch, it stops and the estop flashes as if it has hit the limit switch. It will not back off the switch, the DRO does not go to zero, and it doesn't appear to be recognizing the limit switch is also a home switch, even though I did the auto set up of inputs and it has both the limits and the home on the same pin in the config/port and pins/input signals. Does anybody know what I'm doing wrong? Also, should it home all 3 axes at the same time? Mine only does the Z first, and then I have this problem, so I don't really know if the others are working right or not.
Thanks,
Dave
