I have followed the instructions for how to configure the printer with the Repetier host. I am using a mac so the instructions did not match up perfectly but I followed all applicable fields accordingly. I can control the movement of the motor with the controls +- .0, 1, 10, 100, but the motors do not stop moving in one direction (I have to unplug to stop the motors). Due to this issue I am unable to proceed in the instructions and have hit a road block at positioning the motors. First time using this Form, let me know what additional information i need to provide
