Here’s the carnage! Was running a long print and saw this when I went to check on it. Was running the stock Ender 3 hotend with a Capricorn tube fix for nearly 5 years. Served me well. I haven’t yet been able to remove the white PLA. To see the full damage but, I’m pretty sure that the threads are gone.
Guess it’s time to upgrade the hotend.
True but, with pressure, water can cut metal. I’ll be heat softening it with my PCB toaster oven to see if I can recover it. If it’s just a leak, and no electrical damage, as you mention, it’s probably ok.
Probably, I’ll still get a new hotend, even if there’s no breakage because I think that the PTFE feed tube is a bit of a weak link.
