I´m having this issue where I´m trying to unload the filament, but I get this grinding noise from the extruder (not the hot end but the gears that push or pull the filament), while the filament is firmly stuck.
Upon inspection, I noticed that the temperature first increases, reaching 186°C, but instead of the gears starting to pull at this temperature, the nozzle starts to cool down.
Afterwards, at 107°C the gears start pulling on the filament, but obviously at this temperature it´ll stay stuck to the nozzle.
Seems to me like a coding issue, as the printer instead of pulling the filament at the highest temperature, it skips the operation an pulls when temeprature reaches its minimum…
