Introduction

The xtouch screen is a revolutionary addition to your BambuLab Printer, enhancing the user experience and providing advanced control and monitoring capabilities. This detailed README.md guide will walk you through the product’s features, installation process, and the functionality of different screens.

Required Hardware

Currently, it has only been tested on the affordable 2.8-inch ESP32-2432S028R board, which is available for purchase here:

• ESP32-2432S028R
• ESP32-2432S028R

Optional Hardware

• DS18B20 Temperature Sensor: For printers that do not have an integrated chamber temperature sensor, you have the option to add an external DS18B20 temperature sensor. This sensor will provide accurate chamber temperature readings and enhance the functionality of your xtouch screen. Connector on the screen is 1.25 MZ JST 4P.
• DS18B20 P1P/P1S Chamber Temp Enclosure: Additionally, we have created a 3D model that allows you to easily integrate the DS18B20 Temperature Sensor inside your P1P/P1S printer.

You can buy the Temperature Sensor here:

• Temp Sensor A
• Temp Sensor B

You can find the 3D models

• Model A
• Model B

Powering the xtouch Screen

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:

Powering via USB

1. Connect a suitable USB cable to an available USB port on your computer or a USB power source.

2. At the opposite end of the USB cable, connect the USB connector to the xtouch screen.

3. 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.

Powering via the JST 1.25 4-Pin Connector

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:

1. Locate the JST 1.25 4-pin connector on the xtouch screen.

2. Align the pins of the JST 1.25 connector with the corresponding pins on the xtouch screen.

3. Connect the JST 1.25 connector to the xtouch screen, ensuring that the pins are properly aligned.

4. 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.

5. 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.

Troubleshooting

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:

1. Use a Data Cable:

   • Ensure that you are using a data cable (not just a charging cable) to connect your touch screen to your computer during the installation process. A data cable is required for proper communication.

2. SD Card Compatibility:

   • Keep in mind that SD cards from different manufacturers may behave differently. While many SD cards work seamlessly, some may not be fully compatible with the touch screen. If you experience issues with an SD card, consider trying a different brand or model to see if it resolves the problem.

3. 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:

   • Power off the xtouch screen.
   • Remove the SD card from the touch screen.
   • Insert the SD card into your computer.
   • Navigate to the xtouch directory on the SD card.
   • Delete the touch.json file.
   • Safely eject the SD card from your computer.
   • Reinsert the SD card into the touch screen.
   • Power on the touch screen.

   The touch screen will automatically perform a recalibration process upon startup.
