Steps for Resolving a Hot-End Clog, follow each sequentially until the issue is resolved:

1. Gradually heat the hot-end to a temperature approximately 10 degrees higher than the recommended print temperature for your current filament.

2. Remove the PTFE tube from the hot-end, if present.

3. Attempt to extract any protruding filament.

4. Utilize the Nozzle Cleaner Tools to dislodge the clog by pushing the shaft downward from above. If unsuccessful, proceed to the next step.

5. Use the Nozzle Cleaning Needles to dislodge the clog by inserting the needle through the hole in the nozzle. If the clog persists, proceed to the next step.

6. Execute a cold pull(see below section) and repeat if necessary (refer to the detailed explanation on the opposite side of the page).

If the clog persists despite the above steps, you may need to disassemble the hot-end for thorough cleaning. Follow the steps below for disassembly and cleaning:

1. Heat the hot-end to a temperature approximately 10 degrees higher than the recommended print temperature for your current filament.

2. Remove the PTFE tube from the hot-end, if present.

3. Use the Nozzle Wrench to loosen the nozzle from the hot-end while it is still hot.

4. Allow the machine to cool down and turn it off.

5. Choose a clean, flat surface, preferably a high temperature soldering Mat.

6. Disassemble the hot-end from the machine, noting the order of disassembly and capturing pictures if necessary.

7. Disassemble all subcomponents from the hot-end until individual parts remain. Ensure the removal of the heater cartridge and thermistor.

8. Inspect the inner passages of each component (heater block, heat throat, cooling block, and nozzle) for clogs or material. Apply heat to each part with a small torch or heat gun and use tools to dislodge any remaining plastic. A Q-tip can be used to push out material from the inside of the heat throat and cooling block.

9. Once the parts are clean, reassemble them in the same order, paying attention to ensure a good mating of the nozzle to the heat throat. Additional assembly information can be found in the on our support page or you can contact us for more specific guide or assistance with your printer.
