Describe your issue:

Hello, looking for advice on why my Z steppers may not be moving. There are 3 total. My printer.cfg is a bit of a mess. X and Y work fine and are on the larger plugs on the board. The smaller plugs seems to be the issue and I can’t get anything to work when plugged into them. I’ve tried 8 different known good steppers, wired correctly, and it seems like something is going on when powered up, they just don’t want to move. Someone gave me the idea of more current but fiured I’d check with the experienced folks here first.

On a cursory look:

  • Enable pins needs to be inverted (!)
  • Endstop definition only on first Z stepper
  • Check pins
  • [autotune_tmc stepper_...] is crap IMO

I figured it out… enable pins should have been inverted…

I was just trying it out. I had to change several things already for it and will probably just remove it.
