I am towards the end of an ex controls self conversion from Mach4. Is the machine required to be homed before I can run the spindle warm up? I can jumper across relay 5 (configured for spindle fwd) and the spindle runs. I cannot get relay 5 to close with any of the spindle buttons including the pendent? I cannot home yet as I still need to set up the clear path servos for hard stop squaring.
