Problems with the Z-axis

[PolkCountyMike]

I have finally found a solution to my problem. It is a design flaw in a component on the printer. You can read about it in more detail here: https://blog.honzamrazek.cz/2019/09/test...t-finally/

I believe that the fix for the 2mm short issue is something that isn't in the documentation and that is- after leveling the build plate going back a screen to the Set Zero. This seems so obvious and I'm trying it on this morning print. This was mentioned to me in another forum. Has anyone already tried this step?

I thought of resetting the zero, but on my machine the set zero button is not functional.  When pressed, it shows the message "z-zero is decided by trigger position".  Did you find a way to reset the zero after leveling the build plate?
