Would you mind posting a pic of how you wired your relay
I don't think a picture will really show anything... Just a picture of two wires going to a terminal block.
Mine is labeled "OC out" (it stands for output control according to the documentation) for the relay control. What ended up working is one wire from the +5v terminal to the positive side of the relay "coil"(it's actually a solid state relay) and one wire from the "OC out" to the negative side of the relay "coil". My documentation said that this was pin 17. I then set it up in Mach3 to use that "pin" to turn the spindle on and off.
