I’m trying to print a .stl but when i try to slice with Slic3r Prusa Edition from Repetier-Host (OSX last version) always make a strange layer in the same place, in the preview and in the finish printed piece. When i sliced with Slic3r Prusa Edition and Cura preview it’s perfect but Repetier-Host shows this defect that print in the finish object.
In the last standard Slic3r version looks and print ok.
Repair .stl or changing layer height, etc. not works.
It’s a piece from Thingiverse and i see perfect prints from other users.
