Printing issue - Filament stuck together


Hi since I received my Snapmaker, I was successful in printing the keychain just to ensure the printer is working per design. Since then, I have not been using it. Today, after performing the calibration, during printing the filament would stick to the feeder head and ruin the whole print. I have tried to calibration and clean the head a couple of times with no success. What could be the cause?



When asking for help, can you please provide all the information that you have. What were your print settings, what temperature for the bed and extruder?

Have a good weekend
