Now screw the throat in until it's hard against the nozzle - make sure that you don't place the throat upside down! Usually at one end of the throat the PTFE Tube comes out slightly, this is the end that has to touch the nozzle inside the heaterblock. On the other end, the tube is not aligned with the throat and has a 40° chamfer to guide the Filament into the tube - this is the end that sticks out of the extruder. | + | To fix this, unscrew the nozzle and the throat and clean them.
