This short guide will teach you how to disable the screensaver, or "screen sleep", that occurs after a few minutes of inactivity when using the TouchUI plugin. This will ensure that your OctoPrint touchscreen is always showing relevant information without needing to tap the screen.
Make sure your TouchUI bootloader is up to date by connecting to your Raspberry Pi:
Zachssh pi@octopiThen, run the following commands:
cd ~/TouchUI-autostart/
git pull
sudo service touchui restartIf you made changes to your TouchUI files previously before and receive a pull error, run the following:
git reset --hard
Edit the TouchUI default file using the Nano editor:
sudo nano /etc/default/touchuiChange DISABLE_SCREENSAVER=false to DISABLE_SCREENSAVER=true. Then, press CTRL-X to exit and then Y to save.
Finally, restart the TouchUI service:
sudo service touchui restartYou're all done! NO MORE SLEEP... PRINT THINGS FOREVER.
While making this guide I ran into many Ender 3 V2-specific bumps and stops, and I've worked through them all so you don't have to spend the time.
