Maintenance
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 connect
the 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.
