¶ 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.

¶ Step 2: Install the purge chute
- Align the two bottom latches of the purge chute with the corresponding holes on the inner frame.
- Push the purge chute upward to ensure the bottom latches snap into the inner frame. Support the top of the purge chute with one hand and align the screw hole at the top. Then use an H2.0 Allen key to tighten one fixing screw. Secure the two cables (yellow-green and red-white) into the cable clip on the top of the purge chute.
Note: During installation, ensure the sides of the purge chute are clipped onto the outer edge of the inner frame. Clipping it onto the inner edge may prevent proper installation.
