NEMA 17 stepper motor

I used 17HS4401S 1.8A. They are slightly too large and don’t fit perfectly, but with some modifications, you can make them work.

M3 screws

Various lengths: 6 mm, 10 mm, 15 mm, 45 mm.

Personally, I used an ESP32 Uno with ATD5833 drivers and 1.8A NEMA 17 stepper motors.
Using the Bluepad32 Arduino library, I programmed it to be controlled with an Xbox gamepad.
Once I finish, I’ll share the code and wiring schematic as well.
