Thanks, @apach. I finally determined my problem was some combination of increasing the stepper driver power and that the Z-axis / stepper motor coupler wasn’t perfectly aligned and caused extra tension as it rotated (this could be seen when rotating the threaded rod via the stepper without anything attached to it). I’ve been thinking I may switch to a machined coupler instead of printed, but it’s working great now so what ain’t broke…
