I have decided to switch the RosBot over to Magnetic Carriages, Rods, and Effector as well as replace the J-Head with an E3D V6 All Metal hotend. So I will be designing a new effector, carriages, rod ends, and E3d mount in Autodesk Inventor 2015, my preferred 3D modeling software.

I also picked up the JohnSL FSR Endstop Controller board for greater repeatability with the automatic calibration function.

Once this is all done, printed, and installed I will upload some new pictures of the machine and some sample prints.
