Hi, yesterday I finished building my Prusa i3 but when I tested the movement the steppers just vibrate and move randomly. This is happening for all three axis, I'm trying to figure out what is happening and this is what I tested for now:
- Verified that the stepper is wired as expected
- Verified the voltage of each pololu ( ~400 mv from the potentiometer to GND)
- Now I'm testing each driver and stepper individually
My motors are moving like this one:

I'll upload a video of my steppers if it's needed.
