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, rRun your finger
around the housing. When the nozzle is properly
installed, the clips will be flush with the housing.
4.
Turn the printer on and perform calibration to ensure
that the nozzle and build platform have the correct distance when in the home
position.
5.
Load filament back into the printer.
6.
Perform extruder calibration as detailed in the
CALIBRATION section above.
Note that if the extruder temperature does not read correctly or reaches an unusual
temperature (e.g. 300°C), the new nozzle has not been properly installed. Repeat the above
steps to reinstall the nozzle.
