¶ Safety Warning
IMPORTANT!
It's crucial to power off the printer before conducting any maintenance work, including work on the printer's electronics and tool head wires. Performing tasks with the printer on can result in a short circuit, leading to electronic damage and safety hazards.
During maintenance or troubleshooting, you may need to disassemble parts, including the hotend. This exposes wires and electrical components that could short circuit if they contact each other, other metal, or electronic components while the printer is still on. This can result in damage to the printer's electronics and additional issues.
Therefore, it's crucial to turn off the printer and disconnect it from the power source before conducting any maintenance. This prevents short circuits or damage to the printer's electronics, ensuring safe and effective maintenance. For any concerns or questions about following this guide, we recommend submitting a technical ticket regarding your issue and we will do our best to respond promptly and provide the assistance you need.

- Use an H2.0 Allen key to loosen the 2 fixing screws for the power socket (red square: ST3x8; green circle: BT3x8). Tilt the power socket and pull it out of the inner lining, then press the clip to disconnect it from the power safety key base.
- Lift the transparent protective cover below the power supply. Use a cross-head screwdriver to loosen the 3 screws shown in the image, pull the cables downward, and use an H2.0 Allen key to loosen one ground wire screw (STW3x5). Finally, remove the cables from the clip.
¶ Install the Power Socket
¶ Step 1: Install the power socket
- Reconnect the power socket to the power safety key base. Tilt the power socket and insert it (the screw hole on the left should be inserted behind the post). Use an H2.0 Allen key to tighten the 2 fixing screws (red square: ST3x8; green circle: BT3x8).
- Arrange the cables properly and insert them into the clips in the inner lining. Connect the power socket cable to the power supply, tighten the screws with a cross-head screwdriver, and secure the protective cover. Then, use an H2.0 Allen key to tighten one ground wire screw (STW3x5).
- Secure the power socket cable under the clip and tighten the 2 fixing screws (BT3x12) for the cable clip inside the left inner lining. Finally, connect it to the AC board, tighten the screws with a cross-head screwdriver, and secure the protective cover.
