Problems with the Z-axis

[yaqwsx]

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?

Well, I have. It is not in the documentation as it is I would say 'a design flaw' - what I describe in the post is a fix for the flaw.
