I'm trying to activate the relays on my c23 bob with smooth stepper to handle the run and cw/ccw functions of my VFD using Mach3. In spindle setup I have M3 set to output 1, M4 as output 2. These are assigned pins 16 and 1. The motor relays box is unchecked. In the Mach diagnostics screen M3 and M4 commands illuminate the output 1 and 2 indicators but the relays do not switch.

Any thoughts?

Thanks!
