I installed the bowden hotend set up on the MPCNC and it helped a great deal with the wobble and print quality.
The hotend mount was made by cutting a bowden mount I found on Thingiverse and the extruder set up for the MPCNC. I stuck them together in my 3d program and printed. It was a quick and dirty mesh but it works.
The droid is still coming along slowly. I’m probably going to draw and cut my skins by hand. I can do it on the cnc but the edges are only as sharp as the cutter will allow. A razor is a lot better.
