I am having an issue with my prints where as I print, the nozzle of the printer will run through previously printed material and destroy the entire print. My model is fairly small, a cylinder of about a half inch thickness with a honeycomb inner structure surrounded by an outer solid shell. I created the file in SolidWorks and imported it in as a .STL file into the MakerBot software. Im using the 5th gen MakerBot Replicator with PLA filament. It is just the one model that it does this on, I have printed other models after this and they print fine. Anyone else have similar issues or have any idea where the error is occurring? Thanks in advance
