Brett,
Check that there is nothing wrong with the pc's PP. This is done with a voltage meter. Attach one lead to
pin 2 and the other lead to the cable ground. Watching the meter, jog the x axis + or - and you should see the
voltage change. Do the same for pin #3. You may want to first see the voltage changes from pin 6 or 7 ( your Y axis ) since those pins are working and can be used for comparison.
If not working like the Y pins then you may have a PP problem. I am guessing that you don't have a PP problem.
Turn everything off / unplug pc, contoller, etc. and take a look at the wiring inside the controller box.
Now follow the wires in the controller box from pin 2 & 3 and see if the connection to and away from the driver are ok ( ie; solid connections ). Take a look at how the wires are attached to and from the Y drive and compare
to the x drive wiring ( maybe one is not attached properly ). Without info on your controller i can't be anymore specific.
So as a recap, you checked the pulse signal out of the pc, thru the pc cable to the controller box, cable connection at the controller box to the drive, out of the drive to the connection for the motor.
Hope this helps,
RICH
