Stepper Motor Wiring

[john swift]

you need to use a multimeter ( or a simple battery & bulb continuity tester )to confirm which two wires goes to each motor winding

if you find you have 3 ohms or so between the red & yellow wires connect them to A+ and A- on your driver

you should then find you that you have 3 ohms or so between the
blue & green wires which you should connect them to B+ and B- on the stepper driver

not all stepper drivers have the required fault protection to survive any connection between the A & B terminals

if you find the motor runs the wrong way you can either change it in the controllers software - eg mach 3 changing the direction pin from active high to active low
or
reversing the wires on one winding
eg
changing from
red to A+ and yellow to A-
to
red to A- and yellow to A+
