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.
The EBB board from Evil Mad Scientist (http://shop.evilmadscientist.com/partsmenu/188-ebb) is a much better board. Unlike the one from jjrobots, this is a single board and doesn't require an Ardunio to work. It is also running a different version of the controller firmware that gives much better results. I have used both and the one I got from jjrobots is now sitting in the corner looking for a project.
P.S. Evil Mad Scientist is also in the U.S. so doesn't take as long to ship.
