My printer was intermittently having issues with the clogging and skipping layers, and during my last print, it failed completely. Clogged nozzle, and the filament would not release from the hot end, and broke off inside the hot end... Hate it when that happens....
So tear down day.
I think I found the root issue. The bowen tube has swollen up a bit inside the hot end. The swole section is right at, maybe a bit above the heat break. I think this was letting the filament bulge out, and jam up. Lucky, I have some spare Capricorn tubing that is the right length, and a spare new nozzle. Now to get to get it all back together...
Here is the old Bowden tube. Hard to see the expanded section in the pic, but I can feel it pretty clearly.
