X Nema motor wont work

You can make the motor do that by mixing up two wires. The motor will move back and forth 2.8 degrees and appear to do what you describe.

The stepper motor is +A and -A and +B and -B. Reverse the pins on either the A winding or the B winding.

Feel free to test with test leads, patch cords or protoboard leads as needed.
Much easier than doing it for real and easier to repair if you want the motor to go the other way.
