Z Axis Height Calibration

[tbdad]

When you did it the 2nd time and did the first step of homing the build plate, then did the 0.1mm down 2 times, that actually took it .2mm lower then the home position.

What you would have wanted to do is do the homing position, then instead of the 0.9mm up, just do 0.7mm up, then tapped the z=0 to reset.

thanks, this helped - so "home" isn't going to the zero that you set, but rather goes to a factory default zero position.
i did it again as you said and a corner still didn't adhere to the build plate, so after cleaning the fep again i tried adjusting to 0.5mm up and that did it.  i could re-level (maybe after getting calipers) and get even better but this is nice, thanks.
