Hardened steel nozzle - dummy move
Don’t be a dummy like me when trying to unclog your nozzle: I removed it and use a butane torch to head the end - it blew the nozzle off the body (probably due to the expansion of the differing metals). There goes $55 bucks!
next time I’ll let the Nextruder heat it while I clean it…
RE: Hardened steel nozzle - dummy move
Same happened to me. Now I run a few passes of cleaning filament through mine after a using high temp filament.

Yeah, mine was nylon carbon fiber…

I run "only" hi-temp ASA but this seems a conceptual gap in the whole Core One concept: That the single nozzle is used with incompatible materials, left in an unknown state and the residual contents will just get purged out. It is not that simple.
Only, when it's not, an interface that pretends it is doesn't really help... I use the "controls" menu a lot cramming in PLA for cold pull near the boiling point via extruder axis, cool down gradually feeding material, then pull out at 100 °C while heating back again (otherwise it would get stuck and tear). And this works, e.g. I clearly see the channels of a HF-nozzle in the cold pull plus the debris on repeat attempts, getting less and less.
Slightly OT, but neither firmware nor glossy color brochures guide the user in a direction that would even acknowledge this problem exists.
