It is a pity that my Mach3 computer has been on furlough since March and lies idle in a cupboard awaiting rebuild.

It is impossible to trace your control box wiring as the photos have not shown us the connections of the BoB/Motion controller to the relay that switches on the spindle. Do the blue and black wires connect 5v (or Ground?) to FOR when the relay is energised? I don't know what signals the VFD needs.

You might be able to start the spindle by bridging the relay contacts, if so, then we need to go back and find where the control input for the relay originates and then how Mach3 is meant to activate it.

Can you post a clear picture of the whole of the motion control board please.

Did you get the xml file from the vendor and do you have a Mach3 profile that uses this file?
