I have a couple of things,
1) what kind of part is the captured nut that holds on the filament drivers to the outside of the back of my UM3? Where could I get one/some?
2) I have a flanged up extruder that I can't get out. Images below. The filament is Amazon Basics PLA, and I pulled some of the excess filament off before it cooled.
Yes it is an orange/red filament.
Once I already had the problem I don't think there was a silicon cover for around the hole on extruder 1, and their was one on the second extruder that came off and I set aside after this happened.
Any assistance is really appreciated. This is my printer at home, being retired, it is fun but frustrating to use!
