So here is a clear PLA vase , default size which is pretty big. It printed very consistently all the way to the top (which i know at height some folks have issues).
I cant tell if the banding in this one is normal or not, it is SOOOO consistent.
let me know what you think. Ill print another after new arms

EDIT - THis was done at 210 degrees, 60 degree bed on PEI (perfect) w/ .15mm layer height.
