This is the layout of the pins on the back of your computer.

I am getting 5V dc, between the pins when jogging on the x axis.

Does it go to zero when you jog the other way?

No it does not go back to zero, it stays at 5v in either direction.

Ok well if thats the case and you have not changed any pins since you attached your xml then it seems like your parallel port is not working correctly. Just double check in device manager that the port address is correct, if it  is then looks like your port is bad
 You could get yourself a PCI port if that is the case, they are usually not too expensive.

Well, when I checked the pins, most said 5v dc. When I went the other way with the jog, the voltage did not change from 5 volts...

Only the pins you have set up for Direction pins will change when you jog and only then when you jog the correct axis. For example in the xml you attached you have pin 3 set for X so if you jog the X it should change between 5V and 0V when you change directions. Same for pin 5 if you jog the Y and pin 7 if you jog the Z. Pins 2 4 and 6 should show 0v when still and maybe around 1V when jogging their respective axis.

Alright, so I got that to work.. It will read 0, and around 3.25 volts dc between pin 3 and 25, and 5 and 25... Alright, its not the PCI card, I feel pretty confident about that...

Ok so next thing to do is put the cable on the computer and disconnect from the C10 and do the same checks, some parallel port cables are cross overs so the pins do not correspond and also some do not have all the pins connected.
 If that checks out OK then put the cable back on the C10 then do the same procedure and this time check on the C10s connections to your drives Dir inputs.

Actually, I did the checks with the cable attached to the computer, and read the voltages from the the end of the cable.
