Yes

How did you diagnose that?

Either 65°C or 70°C

I didn’t take the photo immediately - tried cleaning a bit before it occurred to me to document it.

Interesting. All of my prints that failed were running overnight when the temperature dropped.

Thanks. I am really frustrated with myself for letting this happen. Pulled everything apart and recovered most of everything, but managed to damage the clip that holds the extruder in place, so now I get to learn how to do surgery and replace the entire assembly. I wish I had gotten a bit more time before having to do a major repair…

I’ve been printing for two weeks, and I had one.
