That said, just wait until you enclose your printer. The frame will grow in z fairly significantly as it heats up. I’ve not let my printer heat soak, printed a number of sequential parts in one print, and watched the first layer squish getting worse and worse with each sequential part. Eventually filament won’t even stick to the build plate, so you need to tweak z-offset.

Jesus, is that what’s going on… I enclosed my Franken-printer (well it was already enclosed but now it’s less shitty) and my first layer kept growing, I figured it was an inconsistent BLTouch…
