Let's see if we can make it move

Yes!

With an update of STEP on a DRV8834 pololu driver, it moves. However, the motor is to be plugged in a specific way.

It seemed the bobins of the stepper where:

  • Grey (2) + Purple (1)
  • Blue (4) + Green (3) (as per images below)

To have it move, the setup needs to be as follows

  • A1: Green (3)
  • A2: Gray (2)
  • B1: Blue + Purple (1) + (4)
