I have an XYZ DaVinci Mini w which keeps jamming. It does not give a Jam Error. I disassembled the extruder 1 time and found a short piece of PLA stuck in it however that did not fix anything. I've also tried using the Load Filament function repeatedly to try to get the filament out but it does not work. However, after disassembling the extruder, instead of just not printing it makes a loud repeated clicking sound.
