Hello,
I am using a DRV8825 Stepper Driver to run my NEMA 17 Stepper Motor. I have used the minimal wiring diagram as shown below for connecting my motor and am using an Arduino Uno.
However, on giving the supply, there is no motion of stepper motor and the driver becomes excessively hot. When tried with another DRV8825, the setup works fine. Also, the problem is occurring with a newly purchased driver.
The current limit is also set according to my motor(Vref=0.5V, Limit=1A)
Please help.
Hello.
I am sorry you are having problems with your stepper motor driver. Could you post pictures of your setup that show all the connections and close up shots of the board you are having a problem with? What you are using for a power supply? If you disconnect the motor from the driver, does it still get hot?

I am using a Li-Ion Battery of 12V for Power Supply. Yes, the driver still gets hot when the motor is disconnected.
Posting setup pictures soon.
Hello.
Thanks for the additional information. Have you had a chance to take those pictures?
