3D Printer fixes

Well, my Prusa Mk3S+ is back up & running tonight 🎉

I replaced the hotend with a new E3D kit (after shearing off the heater wires a week ago). I thought about just replacing the heater, but I've been having some clogging issues, and thought this would be an easier way to get things back to full operation. I was right - it's printing smooth as butter now.

I also rebuilt the MMU2S, which had gotten out of alignment. It's working again, so I can finally utilize it in the enclosure.
