Maintenance
If you heat up the print head above 50 degrees Celsius the fan should start spinning. If it’s not spinning, please
don’t heat up the print head anymore and let it cool down. See if there are any obstructions in the fan. If there are
any, remove them with some tweezers.
If the fan is still not spinning and there is no obstruction found, the fan should be replaced. Contact our support
desk for more information.

Clean or replace the feeder/extruder motor
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 clean the
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.
Please make sure the printer is power off before removing the extruder motor connector!
Unscrew the two hexagon screws to get the unit loose.
