I have received a new head tool from Lulzbot after the old one broke down. The new one looks fancy and solved the “heat creep”. After printing out for about like 2 weeks, I got a problem. The filament did not extrude and top part of the filament where the stepper motor pushes down the filament into the nozzle has been craved. So I thought maybe it was clogging and I had to clean it.
So I did (I follow videos from Youtube and I instruction from Lulzbot). And it did work but not for long and I have to clean again and again when it failed. I realize with the time that when I was cleaning the nozzle there was nothing making the filament to stop from going doing (no clogs).
So I line the filament kind of 90 degree above the head tool and I made sure that printing does not move around too much. I have my doubts that it will work for ever.
Does anyone have some tips or have faced the same problem?
Thank you and I am sorry for the long story
