TS7-Pro 7-inch Touch Screen
Please refer to Install the Raspberry Pi OS.
• Webcam Option: A camera will need to be installed on this screen for webcam use. Please refer to the tutorial:
Assemble and Use a Camera Module.
• Touch UI Option: A new Raspberry Pi image might not have an auto start function for Touch UI. Please refer
to the tutorial: Touch UI to configure the settings for the Touch UI function.
5.3.1 Touch UI
If the autostart file is not located in the ~/.config/lxsession/LXDE-pi path, the file will need to be
added manually.
Create the lxsession folder and the LXDE-pi folder in the ~/config directory.
mkdir ~/.config/lxsession
mkdir ~/.config/lxsession/LXDE-pi
Copy the autostart file from the path /etc/xdg/lxsession/LXDE-pi to the ~/.config/lxsession/
LXDE-pi folder.
cp /etc/xdg/lxsession/LXDE-pi/autostart ~/.config/lxsession/LXDE-pi/autostart
Set the permissions of the autostart file to be readable and writable.
chmod 644 ~/.config/lxsession/LXDE-pi/autostart
nano .config/lxsession/LXDE-pi/autostart
Open the autostart file with a text editor such as Nano, and add the following line to the end of the file to make the
Raspberry Pi execute the startTouchUI.sh script file on boot.
@/home/pi/startTouchUI.sh
After restarting the Raspberry Pi, the OctoPrint’s Touch UI will open in full screen mode. Press F11 to exit the full
screen mode and enter the desktop.
5.3.2 Make a 3D Model
Click this link: https://projects.raspberrypi.org/en/projects?hardware%5B%5D=3d-printer, refer to the official Rasp-
berry Pi tutorial, you can get the 3D model file in the format of .stl.
Generally, 3D printers cannot directly process .stl files. You need to use Ultimaker Cura software to slice them, and
then upload them to the 3D printer through OctoPrint to print the 3D model file.
Download Ultimaker Cura. Since Ultimaker Cura is not available on the Raspberry Pi system, you need to perform
the slicing operation on your computer.
