Hello everybody,

First thank you to the programmers for this great software
Recently updated to the version 1322 and got problems on the z axis.
My config:
Bottom up printer
I am using gpio.
my Lift After Print are set to 0.2mm
Layer Thickness 30um

but got unrealistic values after updating to the last version(didn't change any setting form my previous release), like down 14.89 and up 14.72 instead of  up 0.2  and down 0.17, and finaly hit the vat
