Install Klipper, Moonraker and Mainsail on the Dell Wyse 3040

Setting up Klipper, Moonraker, and Mainsail on the Dell Wyse 3040 Thin Client is a straightforward process, thanks to the use of KIAUH (Klipper Installation And Update Helper). Unlike some other devices, there is no pre-built image available for the Wyse 3040, but KIAUH simplifies the installation and configuration steps significantly.

This guide will walk you through the process of preparing your Wyse 3040, installing the necessary components, and setting up your 3D printer control environment. By following these steps, you can transform this compact thin client into a powerful hub for your 3D printing projects.

Prerequisites

Before you start, ensure you have the following packages installed on your system:
```
sudo apt update
sudo apt upgrade
sudo apt install git -y
```

Clone the KIAUH repository to your home directory:

cd ~ && git clone https://github.com/dw-0/kiauh.git

Open KIAUH by running the following command:
```
./kiauh/kiauh.sh
```
Select KIAUH v6 (Currently this version is in the testing phase, but I think it will be stable enough for our purposes). To use v6 of KIAUH, enter 3 and press Enter. (This step will be dropped once KIAUH v6 is stable and merged)
Now you will see the KIAUH main menu.

Installing Klipper

Install Klipper by selecting option 1 from the KIAUH main menu to open the installation submenu. Then, select option 1 to install Klipper.
First Question is about the Klipper instances, just press Enter to use the default value (1 instance).
Next question is about the Klipper configuration, press Enter to use the default value (default configuration).
Now KIAUH will install Klipper and its dependencies. This process may take some time, so be patient. (You may enter your password when prompted)
Short before the installation is finished, you will be asked if your user should be added to the dialout group. Press Enter to confirm.
After the installation is complete, you will see the Installation submenu again.

Installing Moonraker

After Klipper is installed, you should be already in the Installation submenu. If not, open it by selecting option 1 from the KIAUH main menu.
Select option 2 to install Moonraker.
First question is, if it should create an example configuration. Press Enter to use the default value (Yes).
Now KIAUH will install Moonraker and its dependencies. This process may take some time, so be patient. (You may enter your password when prompted)
After the installation is complete, you will see the Installation submenu again.

Installing Mainsail

After Moonraker is installed, you should be already in the Installation submenu. If not, open it by selecting option 1 from the KIAUH main menu.
Select option 3 to install Mainsail.
First question is, if it should also download the Mainsail-Config. Press Enter to use the default value (Yes) to download the Mainsail-Config.
Now, KIAUH will ask you for the Port, where Mainsail should run. Press Enter to use the default value (80).
Now KIAUH will install Mainsail and its dependencies. This process may take some time, so be patient. (You may enter your password when prompted)
After the installation is complete, you will see the Installation submenu again. With this short info block above the menu:
Open your browser and enter the URL from the info block to access Mainsail. (In this case, it would be http://192.168.0.37:80)
You should see the Mainsail Dashboard, with the error message mcu 'mcu': Unable to connect. This is expected, as we have not yet configured Klipper.
Congratulations! You have successfully installed Klipper, Moonraker, and Mainsail on your Dell Wyse 3040 Thin Client. The next step is to configure Klipper to connect to your 3D printer.
