Hello,
in general the UM3 works fine for us, but the print quality of the surface where the support connects to the print is really bad.
Picture1: bad print quality where the support used to be, 0.8mm nozzle, with support roof
Picture2: rest of the same print, quality is fine
Picture3: another part, same problem, nozzle 0.4mm, without support roof, just normal support.
Material: PLA
Is this common with Ultimaker/Cura? Or is something wrong?
