again I should note that with the ports and pins configured in the latest xml file I posted (With them setup correctly) the probe and Z switch do work. But the X and Y do not. With none of the switches hooked up to the controller the leds light up as if there is a switch present and active. With the switches plugged in there is no change. The switches he has have LEDS on the switch to show that they are activated. With the switch activated (X or Y) nothing changes in the diag screen of mach. I believe it is a issue with the controller. But we are just trying to exhaust the software possibilities.
