3.2 Auto Post-Print Shutdown (with Panda Touch)

When integrated with Panda Touch, the Panda PWR supports automatic shutdown of your Bambu-Lab printer after a print job is completed. This feature helps conserve energy by preventing the printer from remaining idle and consuming power.

3.3 Local Timer Power-off

The Panda PWR includes a local countdown shutdown capability, allowing you to schedule your printer to power off even if the internet connection is lost. The shutdown timer can be adjusted from the web UI on your phone or PC.

3.4 Dual USB Port Functionality

The Panda PWR provides two USB ports for peripheral power needs:

• USB 1 (Controllable): Ideal for accessories like USB light strips and USB fans, allowing on-demand control.
• USB 2 (Always-On): Supplies continuous power for devices requiring constant operation, such as the Panda Touch. This port allows you to power on the printer via Panda Touch even when the printer is initially off.

4.2 Cleaning and Care

Keep the Panda PWR clean and free from dust. Use a soft, dry cloth for cleaning. Avoid using liquid cleaners or solvents that could damage the device.

5. Troubleshooting

• Device Not Powering On: Ensure the power cable is securely connected to both the Panda PWR and the wall outlet. Verify the power switch is in the 'On' position.
• Cannot Connect to Wi-Fi: Double-check the Wi-Fi password. Ensure your device is within range of the Panda PWR's network. If using the default password, consider changing it for security and re-attempting connection.
• Panda Touch Integration Issues: Ensure your Panda Touch firmware is V1.0.5 or higher. Follow the binding steps carefully, ensuring the Panda PWR is close to the Panda Touch during the process.
• Remote Control Not Responding: Verify that both your controlling device (phone/PC) and the Panda PWR are connected to the same local area network (LAN).
• USB Ports Not Functioning: Check the connections of the USB devices. Ensure the controllable USB port (USB 1) is activated via the web UI or Panda Touch if applicable.
