¶ AMS Interface Board
¶ What it is
The AMS interface board is a circuit board that provides 24V power and also handles communication between the AMS and the printer. For X1E, this board also carries a network cable port for Ethernet connection.
¶ When should you replace the interface board?
Should there be a power supply or communication failure with the AMS. This interface board may also need to be replaced when the Ethernet fails.
¶ Tools and materials needed
- New AMS interface board
- H2.0 Allen key.

¶ Safety Warning
IMPORTANT!
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.
