¶ What is a Silicone Sock for Hotend?
The silicone sock is a black cover that helps maintain nozzle temperature stability by insulating the hotend. Below is what the silicone sock looks like in various 3D printer versions.

¶ X1/P1 Series Silicone Sock
¶ Possible Errors and Malfunction Signs That May Occur When the Silicone Cover is Missing or Damaged
- HMS Error: Abnormality in the nozzle temperature control.
- Temperature fluctuations (unstable temperature): For example, the set temperature might not match the measured temperature and fluctuates inconsistently.
¶ When Should You Replace the Silicone Hotend Cover?
You should replace the silicone hotend cover if any of the following signs occur:
¶ 1. Cracks or Damage
If the silicone cover shows visible cracks or tears, it should be replaced immediately. Any opening can compromise the insulation performance of the hotend, allowing heat to escape and resulting in unstable printing temperatures.
¶ 2. Looseness or Detachment
The silicone cover should fit tightly around the hotend. If it becomes loose or easily slips off, it cannot effectively protect the nozzle and heating block. Cold air from the environment may cause temperature fluctuations and could interfere with the printer’s wiping or leveling functions.
¶ 3. Deformation Due to Prolonged High Temperatures
Extended exposure to high temperatures can cause the silicone cover to stretch or deform, preventing it from fitting tightly or fully covering the hotend. If deformation is observed, replacement is necessary.
¶ 4. Frequent Filament Build-up on the Heating Block
If you notice frequent residue or filament build-up around the hotend, it may indicate that the silicone cover has failed. A damaged cover cannot effectively block oozing or retracted filament, which can lead to clogging and other issues.
¶ 5. Discoloration or Brittleness
Prolonged high temperatures can cause the silicone to age, discolor, or become brittle. If any of these signs appear, the cover is nearing failure and should be replaced as soon as possible.
¶ 6. Friction With Moving Parts (e.g, Nozzle Wiper)
If the cover comes into contact with the other parts of the 3D printer, it may tear or shift out of place. Repeated friction can cause physical wear or misalignment, exposing the nozzle or heating block and affecting heat retention and distribution. It is recommended to inspect the silicone cover after cleaning.

¶ Safety Warning and Machine State Before Starting Operation
WARNING!
It's crucial to power off the printer before performing any maintenance work on the printer and its electronics, including tool head wires, because leaving the printer on while conducting such tasks can cause a short circuit, which can lead to additional electronic damage and safety hazards.
When you perform maintenane or troubleshooting on the printer, you may be required to disassemble some parts, including the hotend. This process can expose wires and electrical components that could potentially short circuit if they come into contact with each other or with other metal or electronic components while the printer is still on. This can damage the electronics of the printer and cause further damage.
Therefore, it's essential to switch off the printer and disconnect it from the power source before doing any maintenance work. This will prevent any short circuits or damage to the printer's electronics. By doing so, you can avoid potential damage to the printer's electronic components and ensure that the maintenance work is performed safely and effectively.

¶ Operation Guide
¶ A1 Series Printers
¶ Step 1 – Power Off and Cool Down the Nozzle
- Turn off the printer.
- Wait for the nozzle to cool down completely.
¶ Step 2 – Remove the Old Silicone Cover
Once the nozzle has cooled, gently pull off the silicone cover.
(If nozzle cleaning is needed, you can do it during this step.)

¶ Step 3 – Install the New Silicone Cover
- Prepare the new silicone cover, making sure the wire groove is positioned correctly.
- Align the cover with the nozzle and push it upward until it fits snugly.
¶ X1/P1 Series Printers
¶ Step 1 – Power Off the 3D Printer and Allow the Nozzle to Cool Down
- Turn off the printer.
- Wait for the nozzle to cool completely.
¶ Step 2 – Open the Front Shell Assembly
Open the front shell and hang it on the carbon rod.
¶ Step 3 – Remove the Old Silicone Cover
- Move the toolhead to a convenient position.
- Pull the silicone cover downward to remove it.
(If you need to clean the nozzle, you can do it at this step.)

¶ Step 4 – Install the New Silicone Cover
- Prepare the new silicone cover, ensuring the wire groove is on the correct side.
- Align the cover with the nozzle and push it upward until it fits snugly.
¶ Step 5 – Close the Front Shell Assembly
Reattach the front shell and ensure all clips are securely in place.
¶ How to Verify a Successful Installation
Visually check that the silicone cover fits tightly around the nozzle with no looseness.
¶ H2D Series Printers
¶ Step 1 – Power Off and Allow the Nozzle to Cool Down
- Turn off the printer;
- Wait for the nozzle to cool down.
¶ Step 2 – Remove the Old Silicone Sock
- Move the toolhead to a convenient position.
- Pull downward and outward to remove the silicone sock.
(If you need to clean the nozzle, you can do it at this step.)
