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.
I’m not sure what you mean by stripped threads. Metal is stronger than plastic, there’s nothing the PLA blob can do to cause physical damage to your hot end besides damaging cables. And I don’t know what threads would be exposed to even be damaged.
I mean if you’re wanting to buy a new hotend by all means get one, but don’t do so thinking you have to because of this. I almost wanna guarantee everything still works as long as your cables are intact.
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.
