Hello everyone, I've encountered a strange problem during equipment debugging: the stepper motor (https://www.oyostepper.es) occasionally rotates in the opposite direction briefly before continuing to run normally.
The pulse and direction signals are differentially output, the wires are shielded, and the ground wire is connected. I've captured the direction signal with an oscilloscope and haven't seen any glitches.
Could it be that the driver's internal logic misinterprets the direction signal under certain conditions? Or is a delay needed between the pulse train timing and the direction signal switching?
Has anyone encountered this situation before? How did you troubleshoot it?
