I’m trying to print a .stl file with a lot of overhang. I ran it through ReplicatorG’s slicer using a profile to add supporting structures. The file doesn’t appear in Pronterface or Repetier Host unless I check show path. It all so appears in the Gcode Plater in Pronterface, but is very wrong in Repetier. Does anyone know how to fix this?
