I've been scouring the forums for the past couple months now and have spent the last two months completely retrofitting new controls for a Bridgeport Boss 5 Series 1 CNC. I'm using a PMDX-126 BOB & ESS, along with the original steppers and Leadshine DM2282 drivers. The first thing I did before my controls were built was wiring the limit switches to NC. With these Bridgeports, as far as the X+Y axis go, its only one limit switch. I've assigned them in mach, and have the limits working properly. However i'm having troubles setting up the homing. I.E., in M4 X axis has --, ++ & Home as the same input. When I try to home my axis it will of course hit the limit switch. I am unable to limit override and jog off because Mach sees + & - hit (my theory). This freezes movement on X,Y & Z axis. I have to manually disable the + axis to jog off the switches, restarting Mach4 several times. Also it seems that if I close Mach when a limit switch has been hit, it won't show it under diagnostics on next start up. It will only show that the limit switch has been hit if I go into the Mach setup screen, and exit out. What am I missing here?
