KlipperUI

USE AT OWN RISK

Tested on Orangepi Zeroplus with Armbian and Beaglebone Black both with Bookworm OS both had this issue here

command to fix issue

sudo echo "kernel.sched_rt_runtime_us = -1" | sudo tee /etc/sysctl.d/10-disable-rt-group-limit.conf

Now reboot the system

sudo reboot now

commands to use script

sudo apt install git
git clone https://github.com/BlackStump/KlipperUI.git
cd ~/
./KlipperUI/menu.sh

This script will now present a menu.

     "1. Install Klipper"
     "2. Install Both Klipper and UI (Fluidd/Mainsail)"
     "3. Install Klipper Linux MCU"
     "4. Change UI (Fluidd/Mainsail)"

klipper-mcu service will not work until klipper linux mcu is flashed!

There will be a menu choice of Fluidd or Mainsail if no choice is made it will default to Fluidd, UI install includes Moonraker and Nginx.

Then continue to setup Klipper for the mcu that you have per klipper instructions here

The Script will install a bare bones printer.cfg if no printer.cfg exists.

The GUI of choice should be accessable so you can edit the printer.cfg from the GUI.
