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've noticed since then that it doesn't connect regardless. I've never realized this because it wasn't a problem during printing. Try to use a brim instead of a raft and give it a shot to see what happens. In reality, at .20 res, that layer just gets deposited on top of the brim and that gap shouldn't be an issue. I remember it took me 1 or 2 tries until it was perfect but that's affordable I guess.
