Pin 2 changes the current state and pin 3 trips as a limit switch. This tell me the software is communicating with the cable.

You are probably looking at the port backwards, look at the drawing I posted way back in the post, it represents what you see on the back of the computer, ie the correct orientation.

I was at the end of the cable instead of the computer. This made it easier to contact the pins.

ok so at least you now know which is pin 11, its what you were thinking was pin 3, so you can now go and check the Step and Dir pins as mentioned previously.

Pin 1 is on the long side far right. I have many pins causing changes on the diag screen. Scratch that, I am looking at it backward.

Can you repeat what I should check now please? I am not sure what we are looking for now. I have spent so much time on this I can't remember what I have tried this time.

Ok look at what pin you have X Dir set to, put your volt meter between that pin and gnd on the port then jog the X one way then the other, you should see the voltage change. Do the same for Y and Z.

There is only .050v showing when the axis is moving but there is 4.42v on pins on 10, 11, 12, and 13 which is always constant, never a change on those pins. What is this telling me? The port is functional but the software is not regulating the correct current? X, Y and Z show no current while moving.

It looks more like a software issue at this point.

I am going to have to take a break and try something different tomorrow morning. I have too many hours on this now. Thank for your help. I'm not sure what to try next.
