The components inside the printhead are connected to the electronics and the extruders through a cable bundle and two Bowden tubes. These must remain positioned the right way to ensure the correct movement and operation of the printhead.
The bowden tubes (blue) must always be located over the cable bundle (white - net pattern).
NOTE: Make sure that the bowden tubes are not entangled.
Additionally these must remain positioned behind the printhead to the right side to avoid getting in the path of the tool changer mechanisms located at the sides of the printer.
