I have a model that a student was attempting to print, but the supports are not coming out correctly. See Attached picture. In some places, the supports do not reach to the edge of the model (blue circles) and in others there are no supports at all where there need to be some (red circles).
The model was loaded into 3D printer OS as an OBJ and converted into and STL with magic fix. I am not sure if this has anything to do with it or not. Any suggestions?
