As I've mentioned, I've been printing a lot on my Ender 3. Unfortunately I missed that the bowden coupler on the hot end had worked loose. This must have caused a gap between the end of the bowden tube and the nozzle which lead to a clog. I cleared out the clog and replaced the bowden tube which had partially melted. Unfortunately the next print clogged as well and a second cleaning attempt lead me to believe that the inside of my heat sync was gunked up and I didn't have confidence that I would be able to get the bowden tube to seat correctly and prevent further clogs.
So after a little research into various hot ends I decided to just go ahead and order a replacement stock one. This particular model has the upgraded Capricorn bowden tube.
I should say here, unplug your printer and it's probably a good idea to pull the sd card as well, just to be on the safe side.
