- Turn on the machine. Heat the nozzle up to 200°C (392°F) by tapping Control > Nozzle.

- Clean the bore. After the nozzle reaches the target temperature, insert a needle, with its diameter smaller than 0.4 mm, into the nozzle bore from the bottom.

Do not use pliers, scissors, or drill bits to clean the nozzle as they may damage the nozzle.
Do not touch the hot nozzle with bare hands.
- Stir the softened filament out using the needle until you have cleared the blockage.

- Check if the nozzle is clean. Tap Load and insert the filament to see if it can get through the nozzle. If not, repeat the previous two steps to clear the blockage. If the filament comes out smoothly, you have unclogged the blocked nozzle. Remove the extruded filament using the tweezers.

If the blockage remains in the nozzle, you may need to replace the hot end.
