Sorry, I forgot to mention, you can go to the Environments and select 3D Print on the toolbar, and then output as an .STL (or just use the File -> Export -> CAD Format -> save as an .STL from here. That is what I'm doing. It's a bit more of a pain, definitely.

There's very few plug-ins for it right now. I assume they are working on them (especially Inventor) and just exporting as STL from Inventor in the meantime.

I have had an issue like that because I didn't notice that the piece that pulls the filament dug a hole in it, and was basically just spinning on nothing while trying to move it. Had to cut off that part and it was ok. Also the PVA can leave chunks in your lines which you can't see, ideally take the one end of the hose off and make sure it is truly empty.
