How to change the nozzle
- First remove the Silicone sleeve from the hotend (If there is a silicone sleeve on the hotend).
- Use an 8mm socket wrench to remove the old nozzle from the heating block.
- To prevent damage to components of the hotend, DO NOT exert force on the throat tube. Hold the solid section of the heating block during adjustments.
- Please preheat the hot end if there is filament sealing the nozzle otherwise the nozzle might can’t be removed. Use a spatula and tweezers to remove the other filament attached in the nozzle or heating block.
- Insert a cleaning rod completely through the hotend and ensure that tube is completely clear of blockages.
- Install the new nozzle into the heating block. Do not tighten it completely. Ensure that there is a visible gap between the nozzle and the heating block.
- Hold the heating block, and tighten the throat tube by rotating the heat sink. Rotate until the nozzle “catches” on to the tube (begins to spin).
- Hold the heating block, and tighten the nozzle completely with an 8mm socket wrench. Check that a gap between the nozzle and the heating block has been maintained.
- Re-attach the silicone sleeve, then loosen the retaining screw on the heat sink. Place the hot end assembly on a flat surface and rotate the heat sink so that the retaining screws face outward.
- Move the heat sink down so that it rests on the silicone sleeve, and tighten it into place.
- If you do not have a silicone sleeve, adjust the heat sink so that it is flush with the bottom of the large cylinder.
- To reinstall the hot end assembly into the extruder head, please refer to Pro2-How to Replace the Hotend.
