I had to rewire some of the electronics on my printer recently. Instead of moving, one of the stepper motors would vibrate. With a closer inspection, I realized the motor was trying to spin in both directions, which created the vibration. I believe there's an error with the wiring of the electronics, but even after several rearrangements of the wires on the motor, it would do the same thing when a signal is sent. I checked my wiring multiple times to make sure it was the same as before with the correct current, but the problem still occurs. All the other motors are working fine, what should I check for now? https://reprap.org/forum/read.php?1,553218,553218#msg-553218 Sun, 15 Mar 2026 13:15:01 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?1,553218,553285#msg-553285 https://reprap.org/forum/read.php?1,553218,553285#msg-553285 For future readers with the same problem:
Try to switch the outer two wires of the 4-pin connector.
