DISPLAY=:0 xeyes - Calibrate touchscreen if needed
3Install OctoDash
- In OctoPrint web interface, go to Settings → Plugin Manager
- Click “Get More” and search for “OctoDash”
- Install the plugin
- Restart OctoPrint
- Configure OctoDash settings (orientation, colors, etc.)
- Set OctoDash to launch on startup
Option 2: KlipperScreen (Klipper Users)
1Install Klipper
If you haven’t installed Klipper yet:
- Flash MainsailOS or FluiddPi to MicroSD card
- Boot Raspberry Pi
- Access web interface (Mainsail or Fluidd)
- Configure Klipper for your printer (printer.cfg)
2Install KlipperScreen
- SSH into your Pi:
ssh pi@mainsailos.local - Run:
cd ~/klipper - Run:
./scripts/install-klipperscreen.sh - Follow prompts to complete installation
- Reboot:
sudo reboot
3Configure KlipperScreen
- Edit configuration:
nano ~/klipperscreen.conf - Set menu structure, macros, and preferences
- Configure screen rotation if needed
- Save and restart KlipperScreen service
Screen Configuration Tips
Display Orientation
To rotate your touchscreen:
- Edit config:
sudo nano /boot/config.txt - Add line:
display_rotate=1(90°),2(180°),3(270°) - Reboot:
sudo reboot - For some screens, rotation handled by driver script
Touchscreen Calibration
If touch input is inaccurate:
- Install calibration tool:
sudo apt install xinput-calibrator - Run calibration:
DISPLAY=:0 xinput_calibrator - Follow on-screen prompts to tap corners
- Copy output to
/etc/X11/xorg.conf.d/99-calibration.conf
Automatic Startup
Ensure touchscreen interface launches on boot:
- OctoDash: Enable “Start OctoDash on boot” in plugin settings
- KlipperScreen: Usually auto-starts, verify with
systemctl status KlipperScreen
