Fitting the filament reels, loading the filament
3
rd
step
• Take the end of the filament, shape as shown in (Fig. 1).
• Push the filament into the PTFE tube as shown in (Fig. 2 ).
• Keep feeding the filament into the PTFE tube until it appears
at the extruder drive screw as shown in (Fig. 3).
Shape the end
of the filament
using wire
cutters to a 4
way point as
shown
Fig. 1
You may find when loading the filament that when it reaches where the PTFE tube leaves the cable chain and enters the extruders it
is harder to push. This is normal and the force required depends on the shaping of the end of the filament
Please see extruder first run section for detail of how to take the filament down into the extruder and running the extruders
When the filament reached this
bend point it can be hard to
push. A well shaped point will
make loading easier
