11.3 Filament Feeding
Mount the spool assembly directly above the extruder (with the extruder as centred as possible). Make sure the
end 10cm or so of the filament is very straight so the it will feed easily down into the hot-end throat (Its can
help also to cut the end of the filament at an approx 45 deg angle). See Fig 11.3a.
Note: To reduce the amount of dust and particles making their way into the hot-end its best to wrap a
small piece of felt or sponge or similar material around the filament secured with some tape, so that it
sits just above the extruder/idler opening. This will significantly reduce the incidence of nozzle
blockages.
