The xtouch screen can be powered in two different ways: through a USB port or via a JST 1.25 4-pin connector. Below are the details on how to power the screen using each method:
Connect a suitable USB cable to an available USB port on your computer or a USB power source.
At the opposite end of the USB cable, connect the USB connector to the xtouch screen.
Ensure that the xtouch screen is turned on and that power is being supplied properly through the USB cable. The screen should light up and display the startup information.
The JST 1.25 4-pin connector is an alternative method for powering the xtouch screen. Here is a pinout diagram of this connector:
To power the screen using this connector, follow these steps:
Locate the JST 1.25 4-pin connector on the xtouch screen.
Align the pins of the JST 1.25 connector with the corresponding pins on the xtouch screen.
Connect the JST 1.25 connector to the xtouch screen, ensuring that the pins are properly aligned.
Provide the proper power through the JST 1.25 connector using a compatible power source. Make sure the polarity is correct to prevent damage to the screen.
Turn on the xtouch screen and verify that it is receiving power properly.
The choice between USB and the JST 1.25 4-pin connector depends on your preference and resource availability. Make sure the xtouch screen receives the necessary power for optimal operation.

If you encounter issues during the installation or operation of your BambuLab Printers Touch Screen, you can refer to the following troubleshooting steps to resolve common problems:
Use a Data Cable:
SD Card Compatibility:
WiFi Connection Loop:
In some cases, users have reported that after confirming their WiFi credentials are correct, the device enters into a continuous loop without establishing a connection. This issue can sometimes be resolved by adjusting the WiFi connection timeout.
To do this, modify the config.json
file and include a numerical parameter for the timeout. Increasing the timeout value can help address this issue.
Use the Online config.json Form for step-by-step instructions.
Endless Reboots in Printer Startup:
Sometimes, users may encounter an issue where the printer and xtouch screen go through an endless reboot cycle during the device’s power-on process, preventing xtouch from becoming ready. This problem can often be resolved by adjusting the “coldboot” value within the config.json
configuration file.
To address this issue, open the config.json
file and include a numerical parameter for the “coldboot” parameter. This parameter specifies the duration in milliseconds the system should wait for initialization after a cold boot. By increasing the “coldboot” value, you provide the system with more time to complete the startup process successfully.
Use the Online config.json Form for step-by-step instructions.
Recalibrating the Screen:
If you encounter touch screen calibration issues or misalignment, you can recalibrate the screen by removing the touch.json
file located in the xtouch
directory on the SD card. Follow these steps:
xtouch
directory on the SD card.touch.json
file.The touch screen will automatically perform a recalibration process upon startup.
