1. Before inserting the bowden tube into the HeatSinks, cut off a small piece
perpendicular the end as to make a perfect right angle cut. This is to eliminate the
gap between the tube and the hotend which will also help avoid clogging.
2. At the motor end of the bowden tube, drill the inside of the tube using an exacto
knife (or another sharp tool) in order to create a small funnel. When loading
filament this will help guide the filament into the tube. Be absolutely sure to
remove all excess from drill remaining before inserting the tube into the extruder
coupling since you do not want this residue ending up inside the hotend as it will
most likely cause clogging of your hotend.
3. Prior to applying filament you must fully insert the bowden tubes (approx. 60 mm)
into the end of the three HeatSinks. If you do not, the HeatSinks will get clogged
and the filament gets stuck!
