Sorry - I have just had a short stay in hospital and still banned from workshop!

Have you managed to identify wire colours? As I say, I can't get outside to check, but there is a quick way to this with 4-wire motors. Best approach is to check resistance (cheap digital multimeter is invaluable!) between pairs of wires - any pairs. If there is maybe some few tens of ohms between two of them, label them as a+/a- (doesn't matter which). There should a similar resistance between the remaining pair - label b+/b-. Connect to corresponding terminals on driver. If the motor goes the wrong way, switch just one of the pairs, + for - and vice versa. Or do it via the appropriate software parameter.

No meter? Take a pair of wires and connect together. If the motor is difficult to turn, that's a pair (as above). Check by disconnecting those and try using the other pair to confirm. Connect two wires that are not a pair and there is no extra resistance to rotation.

Sorry - can't manage long sessions at the moment. Happy to continue discussion, though.
