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 parts that print with the right and left x ends are magnet mounts for magnetic endstops. The hole in the bottom of the Y pillow is also for mounting an endstop magnet. It should be fairly easy to rework for other endstop types, if needed. I used m5 threaded rod, and vinyl tubing to connect the motors on mine, but you should be able to reuse whatever you had before if you like.
