It might still be, but as far as I tested it isn’t. Such a mystery. I still find it weird the vase printed fine but the RC Car piece I modeled isn’t. I tried testing all of the retraction settings and all gives the same result. The 3d benchy boat turned out okay, but had that same issue with certain areas. It has to be retraction cause the pieces that require it are the ones that turn out the worst. The only thing I changed that made it look a little better was the extrusion multiplier to .95 instead of 1. But that’s not really the proper fix.
