1.) Is there supposed to be some kind of little plastic tube inside of the nozzel?
And the big question:
2.) Am having issues with filament wrapping around the gears inside the extruder case. Somehow I think it is melting within the gearbox. Should I add thermal paste between the heat sink and the metal block and between the metal block on the extruder case?
Am not sure what to do.
I will cut the tube as square as possible. I’m pretty sure it goes behind the hot end. I just have to unscrew the thing.
The first time filament melted and wrapped around gearbox was my fault as I turned off the printer without letting it cool (big mistake). So after taking it all apart and cleaning the gears I unscrewed out the hot end and and found this tube there. I thought it was dried filament that had a channel within (like a lavatube ), so I threw it away. It never occured to me there was supposed to be a tube until very recently like 1 week ago.
I got my eyes set on a tube in Amazon but will have to cut it to size.
I then noticed the mk-8 hot end is loose. So I tightened it and it seems fixed because printed the little “cat ring” and it did it without the filament melting inside the gear box. So count this as RESOLVED. thanks everyone.
