I've been searching the forums for a while now and can't find an answer to my problem. I just put a Open Build's Black Box on my C-Beam machine. The stepper motors will not turn. They make a loud noise and then act like they are seized up. After checking the wiring diagram again, I realized I wired them backwards (I followed the Youtube video on the LEAD machine originally). The picture is how they are wired now. I then verified all jumpers were correct inside the Black Box. It still does the same thing. Any suggestions would be appreciated. I used the High Torque NEMA 23 stepper motors (MT-2315HS300AW-OB). I assume these are compatible with the Black Box.
