With a fan cooled, all metal hotend, is there any reason to wait for the hotend to cool, before shutting down power, if the filament has been unloaded?
When leaving the filament on the machine after a print, I’m normally in the habit of waiting until the hotend has cooled down below the filament’s glass temperature before turning the printer off, because without the hotend fan running and the heat block hot, the filament can get softened up in cold end and potentially jam next time. But if there is no filament, would it stand to reason there isn’t enough remaining plastic in the hotend to get heat creep? And it doesn’t matter if the cold end gets hot?
