I had my printer for over a year, and after just a few the filament stopped extracting. I took apart the head, and I wasn't able to remove the nozzle. When I heat it up, not filament comes out the head, and when I try to extrude and retract the filament in console it makes a clicking sound. I contacted you guys right when it happened and I got so frustrated I gave up after a lack of response. So anyways, its about four month later now and I still haven't received a response. I have followed all online tutorials and videos, but none have given me a solution. I am hesitant to blow another 80 dollars on another head, when if it happens to be defective too, I know I'll never receive my money back. What am i to do?
