My 3D printer had problems with its X-axis motor. The motor would stall sometimes. So I thought, could it be the VREF? Checked the VREF, it seemed acceptable. Adjusted it a bit, but still had stalls.
Could it be the stepper motor driver? Replaced it with a spare. Nope, still had stalls.
Could it be the motor itself? So I went on to replace the motor. And noticed that the cable connecting the motor to the board had a problem. One of the wires had broken off at the connector. That was the cause of the problem.
A broken wire.
Not VREF, not driver, not motor. Just a simple broken wire.
Note to self: don't think too much. Start troubleshooting from the basics. 😅
