I figured out my problem above. I’ll post it here as an fyi to others in the future. I was using a 500Hz signal to my driver for stepping when I was getting problems. I upped my frequency to 1k Hz, and it works completely fine now.
I am having some trouble with this motor. I am using a Pololu DRV8825 as my driver. http://www.pololu.com/catalog/product/2132
My motor is able to turn cleanly one direction (counter clockwise), but the other direction is not very consistent. Sometimes the motor shakes violently and it doesn’t rotate as far as it is supposed to. I have wired the motor to the driver in several different configurations, but none have solved the problem. The motor is running off of 12V and set to about 1.4A.
If anyone had any thoughts, I would appreciate it.
