I don’t, but I’ve used numerous cleaning methods and am 99.9% sure that debris isn’t causing the issue. (It still is happening with brand new hot end components right out of the packaging.)
Do you still have the last good config you could try? Do you have different filament as well?
Unfortunately this is the last good config. The printer had literally just finished a print and all I did was change the nozzle (done hundreds of times over the last year of printing) and since then it’s never completed a print. I’ve also tried I think 3 or 4 different rolls of filament, one of them was the filament in the printer when it finished it’s last print, so it was known-good literally minutes before disaster.
Also yes, standard v6 style hotend. I have a couple tests I’d like to run today to try to further diagnose my issue, if the issue somehow points towards the hotend I think I’m going to go for a micro swiss [or look into the hotend you mentioned if it’s a drop in replacement (since I can’t print any new mounting brackets…)]. I really don’t want to get a fancy hotend since this printer is now available from the manufacturer for ~$30 more than the micro swiss. So I’m hoping it’s something else.
