User Manual

4.4.3. Replace filament feed tube

The filament feed tubes need frequent servicing to ensure that the ends will not shear off in the quick releases
during a print. Because the servicing cuts and shortens the filament feed tube, eventually the tubes will be too
short to use and will need replacement. To replace the filament feed tubes, follow these steps:
1. At both ends of each of the filament feed tubes on your printer (1 per extruder, max 5) remove the old
tubes by depressing the blue collar on the quick release, press the filament feed tubes down gently,
then pull them up and out of the quick release.
2. Plug the ends of the new feed tubes straight into the top of each quick fitting on the top of each
extruder, and into the quick fitting on the top of its matching hotend.
