This Adapter Cable will let change the direction of rotation for your 2-phase stepper motor. Useful if your engraving is coming out mirrored (as on some OMTech laser machines).

This adapter changes the pinout as follows:
PIN1 (A+) to PIN3 (B+)
PIN2 (A-) to PIN4 (B-)
PIN3 (B+) to PIN1 (A+)
PIN4 (B-) to PIN2 (A-)

This will only work for a 2-phase stepper motor. If you are unsure, ask!

Do not order if you have a 3-phase or a servo motor.
