Electronics for New Machine + Chinese Spindle + VFD

[mturneruk]

Well got most of the wiring run today, and i thought I would give it a quick test with just the X-Axis hooked up to see if i could get basic communication and motor control.

Having installed the drivers and connected the UC300 to the computer successfully i thought i was home free, however i got absolutely no response in Mach from either the Estop button or the XAxis motor when jogging.

As per the BOB KK01 diagram from CNC 4 You, I have the Estop wired to pin 15 / ground.

There is 5V wired to the UC300 and the BOB, and both have power lights on.
The LPT cable is attached from UC300 to the BOB. Tried both standard ports.
Under Ports and Pins, Mach 3 knows to look for Estop on Pin15 and xaxis motor on Pins 2 / 3 (Port 1).

Have i missed something or is it possible i have a faulty BOB / uc300?

Anyone got any suggestions on how to troubleshoot this ?

Thanks guys
Martin
