Next I identified the wires coming out of the power supply and the voltage which turn out to be 28 volts.

Repeat the process with other 2 motor leads and the other motor.

Because th leads are the same colour I know that is on coil.

Once that is worked out, I cut a dupoint lead in half and soldered each end on to the matching pair of wires.

If it was open circuit, grab another wire and check that, you are looking for a pair of coils inside the motor, so you need to match up to ends of each coil (which are connected to to each wire).

Grab any 2 wires on you stepper motor and check if you get a reading you should get either open circuit or a low resistance.

Set your multimeter to the 200 ohms setting.

The next step will show you where all the wires go but first we need to identify the four wires on our stepper motor. Once that was done it was time to start using some of those dupoint wires, they make every thing very easy to wire up Just pull a pin out of the headers and plug it in if you want to make the end of the wire male. The first thing to do is to work out where the Arduino, relay and easy drivers are all going to fit, so I removed all the old electronics and made up a laser cut board for everything to mount on.
