I have located this thread in projects as it is a work-in-progress (WIP), when I am satisfied with the end results I will be moved to Mods and Upgrades. I am a bit concerned about the longevity of the plastic extruder that is used on the C2 / R2 series of printers. I have had an E3D Titan Extruder almost from the first day it was released. It was still in the box, unused. So what better way to use it than to upgrade the current extruder with this one. For those that want to modify the top for their own use, here is the link to the A360 web details. The model was created with Fusion 360. The link will also allow downloading in various formats if you do not use Fusion 360. (Link removed) I have printed this with PLA as a test. You need to support the top section (where the Uptown board attaches). I am going to reprint in polycarbonate before actually installing it.
