Tell us about yourself!
i've tried to make one by myself. The structure is OK, but i've some issues with stepper motors, cause they don't work. I give you some informations about my circuit:I've used A4988 drivers, and i've soldered the solderless wires (wires of the breadboard) on motors' pins (and i'm not sure if this was a good idea :/). I'd be grateful if you could help me.
