I printed the calibration cube and got about 20x20x16. I tried changing the steps_pr_mm_z to multiple values, but don’t seem to be getting the change in the Z axis that I would expect. Is there a procedure for calibration?
Turns out I just needed to keep trying, I eventually found a value that was about 20 steps-per-mm higher than my calculated value for z
Good to hear that you got it sorted!
