Now take the end of your filament and using sharp side cutters or a hobby knife snip the
tip off at a sharp angle, this helps the filament slide through the feeder and print head
easily.
To start loading use one hand to hold the charging handle and the other hand to push
the filament through the Bowden tube connector and along the Bowden tube until you
feel a slight resistance, this means you have reached the extruder where the path
narrows and the filament now needs to be pushed a little harder to get through this. It
is important that you do this next step in a single forward motion and that you don’t pull
the filament back at any stage as this can cause the filament to form a plug which will
block the extruder. You will notice that the filament becomes slightly easier to push
through and a thin stream of filament will begin to be extruded from the print nozzle, the
extruder is now charged and ready to print.
Tip:
To make it easier to thread the filament you can disconnect the Bowden tube and
pull through some filament slack so you don’t have to hold charge handle while pushing
the filament through extruder. Once you have the extruder charged, hold the charge
handle and push the extra filament back towards the roll until you can reconnect the
Bowden tube.
