I was searching for an issue and came across this and figured i would ask, i have 10 of these printers (i work for a school) and they all print wonderfully with the standard profile and little to no modification.
We just got an 11th and it doesnt print nearly as good as the others. I have tweaked the retraction distance and speed to the moon and back, coasting on and off, extra restart distance back and forth....no dice.
For some reason it always comes out with extra material right near the start and stop of each layer (see pic)
anyone else have this issue?
