Changing the print head

LARGE VOLUME series 3D Printer

PRO series 3D printer

DESK series 3D printer

LARGE VOLUME series

The print head can be changed quick on a LARGE VOLUME series 3D printer. Just follow the steps below.

Unload the filament

Make sure you unloaded the filament if possible. If this is really stuck, continue to next step and cut the remains of filament. Remove the Bowden tube from the print head. Lower the print head by moving the printer to the maintenance location.

Press Macro > Maintenance

Remove the blue clip (if present) from the print head.

Press the black ring (pneufit) down with your finger and pull the tube upwards away from the print head

Cutting stuck filament

Sometimes the filament is really stuck inside the print head. In this case you want to change the print head but the filament is holding you for a quick swap. If you have a SLA cut the filament just 5cm (2 inch) above the printhead and sent it back to the Tractus3D clean center.

Disconnect the main cable

When the bowden tube is disconnected, unscrew the silver connector of the print head from the main cable.

Disconnect the arms from the print head

Now unscrew the 3 silver screws next to the fanduct and printhead

Take out the printhead like the picture below

Installing new print head

Put back the printhead on top of the 3 holes in the effector (plate) and screw the 3 silver screws back in place.

Secure the main cable to the print head by plugging in the connector and tighten the screw fitting. Push back in the bowden tube until you can’t get in any further. Place the blue clip (if present) back under the black ring of the bowden tube. Restart the printer by turning it off and on again or pressing the STOP button on the LCD screen
