Ran into a problem with my router last night and am looking for assistance and/or ideas to troubleshoot.

The router is using a ethernet Smoothstepper, generic bob (port 1 on the SS), PMDX-109 output board (port 2 on the SS) & a CRP550 Bridge board.

I powered on the machine, ran the home routine and powered up the spindle to warm it up. Everything moved and worked as it has for the last 3-4 years.

Then I loaded g-code and attempted to jog to where I could set z. No movement! And I'm unable to trigger the PMDX-109 relays.

I've confirmed that the steppers have power, they're locked and the power supply is outputting 48vdc.

The Smoothstepper is connected to the PC (LED lit) and see's an estop (red led lit) if I trigger it.

Mach3 shows the probe active if I touch the z plate to the bit. Mach3 DRO's show movement if I jog manually.

All boards are powered, no changes to Mach3 configs, etc.

Yet no movement of any kind, spindle doesn't power or, relay's are not being triggered.

Suggestions of what to look for???
