MakerBot Print is our newest print-prepration software, which supports native CAD files and STL assemblies,
allows you to interact with all your printers via the Cloud, and many other exciting new features.
I configured my printer very closely to what you have - prior to reading your post - and I am having the exact same issues with the same back teeth. I had a load error and I started (at first) at 100% - at an estimated time of 24.5 hours - I decided to reduce the size to about 50% and it cut a ton of time off.
Well, I am going to try it again with different supports.
