9. Maintenance
9.1. Lubrication
Once a month, lubricating the cylindrical guiding rods X Y Z is required. To that effect,
lubricating oil for home appliances should be used. The lubricant should be applied on 5–10cm
of the guiding rod length.
9.2. Replacement of Filament
Here is how to replace the filament:
1. Switch on the 3D printer and heat the extruder up to operation temperature.
2. Double click the selected arrow in the [Manual Control] tab of Repetier-Host :
Filament feed shaft will start reverse rotation.
The filament will be driven upwards, instead of being squeezed through the nozzle.
3. Upon completion of the 3D printer commands, the filament will not be pressed to the feed
shaft. Take the filament out by your hand.
4. Switch off the sustaining voltage of the motors using the button:
5. Remove the dust filter.
6. Open the filter and replace the polyurethane-foam filter cushion (if needed).
7. Cut the filament end at an angle to sharpen it.
8. Force the filament through the filter cushion and push the filament into the extruder until it
appears from the nozzle (hold the sliding cradle with your hand to avoid the deformation of
guiding rods).
