Im just about to connect my stppers to my drivers, but am not sure what is what as the connections are labled 1a 1b 2a 2b, how does this relate to a+ a- b+ b-. the instructions say "First phase connected between 1A and 1B
and the second phase connected between 2A and 2B".

Thanks

Do your stepper motors just have 4 wires each?

Do you have a multimeter that you could use to make resistance measurements of your stepper motor wires (in order to verify which pair of wires represents a single winding)?

My inclination would be to treat 1a as a+ and 1b as a- (and similar for 2a as b+ and 2b as b-), but that's just a guess.
