WARNING: Please make sure the printer is power off before removing the extruder motor connector!

The feeder leads the filament to the print head. To ensure that the exact right amount of filament is extruded,the feeder gear needs to turn turn smoothly.

Small filament particles might remain in the feeder after many hours of printing. We recommended to cleanthe inside of the feeder after three months of use.

The following steps need to be performed

  • Heat up the print head and unload filament (see chapter 7.2 Unload Filament)
  • After filament is unloaded let the print head cool down. Never turn off the printer with a print head above 50 degrees Celsius!
  • Lower the print head by moving the printer to the maintenance location.
  • Press Macro > Maintenance
  • Turn off the power of the printer with the front switch.
  • The feeder (also know as extruder motor) is mounted on the ceiling inside the printer.

Here you will find a silver/black feeder unit with an extruder motor attached.

  • To clean this motor and gear, you need to remove the motor from the ceiling for easy access.

This can be done with only removing 2 screws and 1 connector

Unscrew the two hexagon screws to get the unit loose.

Disconnect the white connector gently

Now you can clean or replace the gear from the extruder unit. The gear is locked with a set screw. If you replace this gear, make sure the set screw of the new gear is locked with loctite or a similar product and the setscrew is not sticking out of the gear unit.

To easily clean this gear, you can use a toothbrush or brass brush while slowly spinning the gear with a finger.

  • After cleaning or replacing the gear make sure you carefully connect the connector on the motor again. Watch the connector closely as it will fit only in one way. You don’t need a lot of pressure to connectthe connector.
  • Push the small Bowden tube through the hole in the ceiling and roof.
  • Screw back the two hexagon screws make sure the extruder is mounted the right way and no cables are between the mount and ceiling.
