@GME No problem. I didn't know for certain it was a driver issue either. Posting here was a bit of a shot in the dark.

Some new drives are on the way, hopefully that turns out to be the issue : )

Thanks. I switched your pinout. I'm glad to have it configured correctly, but unfortunately it didn't fix the problem.

Hmm ok. I'll try to verify the current getting to the motors. Why would a lack of current cause this?

I tried a bunch of different acceleration settings from 1 up to 60 and none of them really changed the reversing behavior. It's possible that what I'm seeing is normal, but I haven't see this...

P1 pin 2 (stp) -> 7I76s TB2 pin 3 (step0+)

I did try decreasing the acceleration. It didn't seem to do anything, but maybe I should take it super low and see if it helps. I'll try messing with the tension next while I wait for a response from...

I don't think there's any backslash compensation. There are settings for it in pncconf, but they're all turned off.

This happens with all of the motors and each one is on a different output.

I’m using a Mesa 7i76 breakout board.
