I have only been printing for about three weeks now. I started on an iron man helmet and I'm about three-quarters of the way through. Took a break from the helmet and did a fun pop jason From Friday the thirteenth. Then I noticed that my hot end housing was loose so I tightened it up, And started to resume my print when it would not lay down a thick line it would build up around the nozzle, and then drag it around the plate to get a big old ball Mess. I checked the extoutor And the filament going into it would back up and then go forward back up and then go forward which to me look like nothing was going into the extoutor. I changed the nozzle check to see if the hose was touching the nozzle everything looked okay. I have almost settings at the right position it will not stick to the plate no matter how many times I clean it. Can somebody tell me what's wrong please help
