I literally just got my Saturn 4 ultra two weeks ago, it prints PERFECTLY right out of the box. I literally did nothing to set it up. I'm so used to my CR10 needing to be babysat it was shocking how well the prints come out.
I have heard of them losing their Z position and ramming the build plate into the reservoir repeatedly, but that the only problem I have really heard of them having.
Maybe yours has a defect?
This annoys the shit out of me on a daily basis
