Can anyone share any help or experience with the stepper motor voltage adjustment pots on the TinyG. I’ve got my OX running but haven’t adjusted the pots. Is this something that’s needed? If so does anyone have a general setting I can start off with? Seems like Synthetos recommends doing this before mounting the motors but I missed that step. Thanks!

I’m using the openbuildpartsstore NEMA 23 & 17 steppers. I set the pots about 1/2 way, which seems to be enough current to make things works and not too much that the steppers run hot.
