LOADING THE FILAMENT (continued)
3 Begin heating the extruder
After you've finished feeding the filament all the way through the guide tube,
make sure that the extruder has time to heat up before loading the filament.
Heat up the extruder by selecting the thermostat or "extrude" option in the LCD
touchscreen menu.
WARNING: Never touch the extruder while it is heating — it heats up to 220° C.
4 Inserting the filament
After the extruder reaches the correct temperature, move the extruder switch to
the left into the "unlocked" position which will allow the filament to bypass the
gears. Insert the filament into the extruder hole as far as it will go. When you see
the filament begin to extrude, first return the extruder switch to the right side
into the "locked" position. At this point you can also use the "extrude" menu in
the touchscreen to push for filament out of the nozzle.
5
Re-inserting the filament guide tube
Re-insert the filament guide tube back into the hole at the top of the extruder.
6 Remove the excess extruded filament
Wait a few minutes for the excess extruded filament to cool down and then
remove it by hand (best with gloves) from the nozzle. Make extra sure not to
touch the nozzle, it will burn you. If you leave excess test-extruded filament on
the nozzle, it may redirect the later extruded filament, causing it to not stick to
the build plate, which could possibly ruin your print.
