Setup a M545D driver with a stepper motor

Miss wired motor.
Stepper motor, how many wires ?

I have had 8-wire motors where the wire colours in the data sheet were completely different to the motor. (Well, the colours were the same, but they were connected differently)

1) Work out which wires are the ends of each winding. You can do this with a multimeter, or, choose one wire and see which wire, when held touching it, makes the motor harder to turn. When you find a pair, make a note, and tty to find another pair. Make sure that no wires touch other wires, though.

2) Once you have the pairs you need to work out which ones are A and which ones are B. I have forgotten how to do that..

3) However, I do remember how to work out the polarities. Take both of your A pairs, and connect two of the wires together, Then connect the other two. If the motor is stiff to turn then either of the current connections can be a centre-point. If the motor remains easy to turn, swap one pair end-to-end, and then try again.
Basically with the correct polarity they add, and the motor feels stiff. With the wrong pairings they cancel, and it is as if there is nothing connected.

To check if a pair is A or B and to check the polarity I used a 9 volt battery: if two pairs are A with the same polarity I can't run the motor otherwise I can.

I think that you will get the same result if you have one half of A and one half of B (with any polarity?) That's one of the half-step positions.

I think that you can probably tell if you have both halves of a phase by checking that there is no half-step if you power the second pair of wires with the first pair already powered.
