As long as you can get the part number of the stepper chips, and find a datasheet, just trace the PCB tracks. Or there will only be 2 tracks that go to dedicated pins on the controller chip from each stepper chip, which leaves only two options as to what is the step and dir.
So if if i power the BOB from the 5v of the conect board will that not work?

Yes I will replace the stepper drivers but I would like to use the DC spindle motor?
You really need to find out what the spindle drive is. Mine was a SCR style drive (very common for DC motors), which means the speed control terminals are at near mains voltage. Connect them to anything other than an isolated 0-10V, and something will be releasing magic smoke.
