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.

Next, press the power switch socket into place until you hear a "click" sound, indicating it is securely installed.
2. Install the AMS HT Main Frame
Connect the two cables:
- Mainboard communication cable (14-pin).
- Mainboard power cable (2-pin).
Connect the power socket cable to the mainboard and reinstall the insulation sleeve.
Note: Polarity does not matter here.
Connect the front screen cable and secure it in the channel.
