I actually get the .025v all the time, it doesn't matter if the axis shows movement. I wonder if there is a way to check the parallel port if I take it to the computer shop? Although I am not convinced it is the motherboard/port.

Is that the direction pin for the axis you are measuring at? If it is have you jogged both ways as you will see 5v one way and 0V the other.
If it is the step pin then you will probably be seeing correctly as it will be 0v at rest and because it is a pulse coming out your motor will read the average voltage of the pulse which will just be mV which is what you are seeing.

You are so right!! I read 4.45v on all three axis' in one direction when jogging. So now we know we are getting voltage but I want to do it with the cable plugged in to rule out the cable.

At the end of the cable there is 4.45v on all Dir pins. Now what?

Here is a question. If I jog x axis both ways, I also get 5v on the BOB corresponding pin screw. So the motor drivers are seeing the correct voltage. This is working for all three axis' including the slave which reads the same as its host which is X. Now what?

You will need to look in the manual I dont know what drives you have. If you attach the manual I will look. Also these Chinese drives require an enable, you can have a permanent enable like on your BOB but check out the wiring diags in the manual. The other thing about these drives is they can be set for CW/CCW or Step/Dir, you need them set for Step/Dir
