-To fix this, unscrew the nozzle and the throat and clean them. Screw the nozzle back in until there is 1mm space between the nozzle and the heaterblock. Now screw the throat in until it'hard against the nozzle. Make sure that you don't place the throat upside downUsually at one end of the throat the PTFE Tube comes out slightly, this is the end that has to touch the nozzle. On the other end the tube is not aligned with the throat and has a 40° chamfer to guide the Filament into the tubethis is the end that goes into the extruder. +To fix this, unscrew the nozzle and the throat and clean them.
