Home position problem + goos skirt, but then pants :-(

The first thing I do with a new machine is to change the bed level nuts for printed ones with nylock locking nuts inserted.
Pretty much solves the bed levelling. I level Maybe once a year, maybe less :-)

The other thing you can do is to adjust the z-gap in the slicer. So you can try making the gap larger or smaller.
in prusaslicer it's here:

I usually adjust by 0.1 mm increments. so positive numbers to make the gap larger: 0.1, 0.2 etc and negative valuse to reduce the gap: -0.1 etc.

And yep 3d printing is pretty amazing.
Still blows me away that i can think of a widget and design it and hold one in my hand an hour or two after thinking of it.
