Replacing the Nozzle
Improper operation or the use of low quality or old filament can cause blockage in the
nozzle, which may require the nozzle to be replaced. Perform the following steps to
replace the nozzle.
1. Unload the filament, then turn the printer off.
2. Use scissors or side cutters to remove the ties and the wrapped cloth.
3. Unplug the nozzle connection plug.
4. Loosen the buckles on each side of the nozzle fan, then remove the fan cover. Use
the 1.5mm hex wrench to loosen the lower side nozzle fixing set screw, then gently
pull out the nozzle from the bottom.
5. Install the new nozzle, then tighten the set screw to secure it in place. Plug in the
connection cable and put on the wrapped cloth. Use cable ties to fix the cable in
place. Finally, install the fan cover and fix it in place with the buckles.
6. Turn on the printer, then select Prepare > Delta cal to perform the automatic
calibration.
