I am using DRV8825 to drive my Biploar Stepper motor. Name of my stepper motor is KS42STH34-1504A, which according to my internet search has 1.5A current/phase . I have been trying to set the current limit, but so far i have not succeeded in doing so.
I am connecting 12 V, 1 Amp PSU to Vmot, and i am connecting Arduino Uno 5V to RESET and Sleep pin. As long as i turn on the only12 V PSU, DRV8825 doesnt heat up and i get 0V at potentiometer. As soon as i turn on my arduino and provide 5V to Reset and Sleep pins, DRV8825 get very hot and i read 0.025v at the potentiometer and 12v at the hole near M2 pin.
I dont know what is wrong with the connections. I have made connections similar to the one made in the website. I have not connected the motor yet.
I have used
- white wire for ground connections.
2.red wire for Vmot
3.gray and maroon wire for reset and sleep pin which is connected to a to +5v of arduino uno through bread board.
Thank you in anticipation.
