Stepper motor only moving 1/10

Stepper motor only moving 1/10

I just got my ramps board figured out but I can't get the stepper motors to move. I have only 1 plugged in for now and I send commands using repetier and it doesn't move. Repetier also reports strange steps using the manual controls.

I have:
Arduino 2560
Ramps 1.4
DRV8825 drivers

FIGURED OUT!

New problem:

The stepper only moves about 1/10th of what it is supposed to. Anyone know how to change movement distance? I'm using repetier as it is the only one that would work with my drv8825's.

Looks like the steps/mm setting needs calibration.

Yeah, I've fixed the problem. Now need to figure out how to tune the motors so they don't have a high pitched whine.
