@hwalker_MIWV, You can test the stepper motor with your multi meter. Measure the resistance of the wires against each other. For a bi polar stepper wire there should be 4 wires, typically red, blue, black and green. Two wires should so low resistance (i.e less than 100 Ohms) which the rest should be practically infinite.
If the motor moves then stops then you may be getting an over current problem (like I do).
