Just read an article suggesting 100 microns is the default assumption for accuracy.
I'm a LONG way from 100 microns... lol.
I guess it's time to default all the settings, run a new calibration cube, and start adjusting from there. I was hoping I could fix it with some minor scaling in the slicer rather than diving in, but that's not to be (that's how I ended up with this latest one, which is slightly better than the last, but not much).
This hobby takes more patience than reloading, I swear it.
