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.
It's not just the parallelogram that's formed by the frame that improves stiffness. It's also the additional triangulation that occurs where the Z smooth rods meet the bottom frame.
Handling the Akimbo frame, it feels far more rigid than the Sells or Prusa frame, but it's still possible to push the top out of line with the bottom.
Still, increased frame rigidity was not my primary goal. I'm after increased build area, particularly when running two extruders.
