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 have never had the original HEVO print however I did have it assembled and there was quite a bit of rotational flex on the X axis as well as flex between the X and Y joint (I could pull the one side towards the front and the other towards the back). Using the rails I have almost no flex, it takes a lot of force to flex either. See the attached image.
