At the beginning I want to apologize if I make any mistakes in english, I’m not a native speaker.
Recentlly I bought DRV8834 stepper motor driver (Pololu - DRV8834 Low-Voltage Stepper Motor Driver Carrier) to control stepper motor. Unfortunelly motor haven’t run or only made few steps when voltage was supplied and then stopped making some noise ocassionaly . I used minimal wiring diagram from polulu page. I also set up current limitation as shown in polulu video. What I’m using in this project is:
-Arduino Uno Rev3 (powered by USB)
- Stepper motor JK42HM48-0806 (400 steps, 6V, 0.8A)
- DRV8834 from polulu (powered from arduino 5V pin)
- Li-Pol Redox 1300mAh 7,4V 20C for motor power supply
I’m not an expert but I have theory that DRV8834 can’t “push” enoguh current to motor. I have tried to adjust current limitation but it didn’t changed anything. For me the weirdest thing is that sometimes motor is buzzing like he wants to make a step but it doesn’t and then motor just goes silent.
