RE: 6.4.0-RC Firmware for Prusa CORE One
Jan, you might want to have someone look at https://github.com/prusa3d/Prusa-Firmware-Buddy/issues/4835 too, at least for triage. I'm quite sure it's a bug that was introduced with 6.4
While a nozzle staying at 250º C or whatever for potentially hours on end is not immediately bad, it's not good either. I didn't test beyond probably about an hour, which happened by forgetting that I had to walk from the printer to my laptop and send it the signal to stop heating the nozzle.
Not sure how crispy/crusty things will get inside the nozzle or if the filament simply oozes out quickly and it's just bare metal being heated.

Hi. Our DEV team is aware of it.
Just to be sure, try to replicate this issue with 6.4.0 RC.
RE: 6.4.0-RC Firmware for Prusa CORE One
Yes, very much reproduces still on RC. Will comment ticket.
