@brent oh and here is the real weird part - the skirt around the object is always perfectly ~0.2m high - this only seems to apply to the object itself

printing a whole benchy in that location now (already printed benchy base in that location as part of the test that [produced these](https://forum.snapmaker.com/t/is-a-consistent-first-layer-across-whole-of-a350-build-plate-actually-possible/20740/25), they were scattered all across 1/2 the build area)
