My original part worked fine: it was NOT a problem of alignment (did you try the attached FZZ file?) but, as you mentioned, a question of pins genre. I moved the connectors in breadboard slightly so they all align and now that works Unfortunately the current breadboard doesn’t align on 0.1in boundaries so that doesn’t work. I assume because the stepper has female pins you were hoping to be able to connect the stepper to the module in breadboard and have it connect.
