  • Hi,

    I recently buy this driver, with a NEMA 23 stepper motor, and with Arduino, I have tried to move it, but I can not. I have used a circuit similar to reprap 3d printer (Arduino controls ENABLE, DIR and STEP) and the other pins are fixed, but the motor does not move. I have noticed that the voltage regulator, it is heated up, so I think this component is damaged. Is there any way to check I am correct? Are there other explains? What is exactly the voltage regulator for replace it?

    Thank you very much, Antonio.
