I’m working on a stepper motor project with a custom PCB that requires me to rotate two stepper motors at the same time. I’m using two DRV8825 MOSFET and an 8 channel relay, with four relays attached to one stepper motor and the remaining four to another.
The stepper motor rotates during the NC state (when the relays are turned on). The issue I’m having is that one of the motors on the J9 connector doesn’t step, and it doesn’t even vibrate when the relays are turned on. I’m not having this problem with the motor when it’s attached to the J10 connector. Any help or advice will be great!
