CLEARING A CLOGGED NOZZLE
From time to time, the nozzle will become clogged with filament material. Perform the
following steps to clear a clogged nozzle.
1. With the printer powered on, touch Filament > Change to remove the currently
loaded filament. Pull out the filament once preheating has finished.
2. Carefully insert the included Unclogging Tool into the nozzle while turning it to
"drill" into the material, then pull it out while turning. Repeat several times.
3. Using a pair of scissors or side cutters, diagonally cut the end of the filament so that
it comes to a point.
4. Insert the new filament into the feed mechanism, then touch the OK button to
allow the printer to feed filament to the extruder.
5. Once several centimeters of filament has been extruded, touch the OK button to
stop extrusion.
REPLACING THE NOZZLE
This printer features a quick disconnect nozzle, allowing for easy replacement. Perform the
following steps to replace the nozzle.
1. Remove any installed filament, then turn the printer
off and allow all parts to cool before touching the
extruder and nozzle.
2. Squeeze the two clips at the bottom of the extruder,
then pull out the old nozzle.
3. While still squeezing the clips, insert the new nozzle.
Ensure that it is fully inserted and fully seated in the
extruder. After inserting the nozzle, run your finger
around the housing. When the nozzle is properly
installed, the clips will be flush with the housing.
