Information on how to read and set the value for the current limiting potentiometer can be found in the “Current limiting” section on the product page for the DRV8825 carrier board. Additionally, the video in that section might be helpful:

If you continue to have problems, could you tell me what you set the Vref voltage to and post pictures of your setup and your board.
