can't get my steppers to work (RAMPS 1.4/Marlin)

I'm trying to assemble my electronics, I got Marlin to install into the RAMPS board, got the LCD working. But I can't get the stepper motor to work. I assuming the motors should lock up once the board is powered up? I tried to move the driver and motor to the other axis (X and Y) but it still freely turns when I power it on. I put all 3 jumpers to make it 1/16 microstep. The pot on the stepper driver doesn't have an end limit, freely turns counterclockwise forever. Is there anything I'm missing?

Thanks

I figured it out. I was using the round AC adapter plug on the Mega board, I cut up the plug and attached the power directly to the terminal screws on the RAMPS board. Was the stepper motors are able to lock up when activated.
