I am new to 3d printing having only recieved it for christmas. The filament is jammed somewhere in the extruder of my Wanhao Duplicator i3 Plus. I have tried removing it with the included hook but was unsuccessful. Is there anything else I should try before I before I dismantle the extruder, which i very much want to avoid.
Try to preheat your printer, the temperature should be above 180°C then push the filament to come out from the nozzle just 4 to 7 mm, then take out the filament from the extruder. With this step the plastic lump will get soft and will release the filament.
Then use the tool to clean the nozzle pushing the residue inside the nozzle.
This is a common problem if someone tries to change the filament without feeding a little bit (3-5mm).
