How to Install FluiddPi on Raspberry Pi

In this guide I will show you how to install FluiddPi on a Raspberry Pi. I will use a Raspberry Pi Zero because it’s a cheap option for running Klipper but you can follow the same guide for any Raspberry Pi variant.

What is FluiddPi?

FluiddPi is a Raspbian image similar to MainsailOS which comes with the Fluidd web interface and Klipper already installed. The interface is lightweight and responsive, which means you will be able to use it on your smartphone with ease.

Fluidd allows you to connect and control multiple printers, it has thumbnail support for Prusa Slicer, has automated updates, a bed mesh viewer and camera support.

Prerequisites

  1. Raspberry Pi 
  2. MicroSD Card – High Speed MicroSD Card is recommended
  3. Good power supply for the Pi – Any adapter works if it’s capable of delivering at least 2.5 A of power

Install FluiddPi on Raspberry Pi

Flash FluiddPi on the SD Card

Before we install FluiddPi we need to first download the latest release from Github. At the time of writing this guide, FluiddPi reached V1.11.2.

Download the FluiddPi image then unzip the archive.

Download and install Win32 Disk Imager.

Download Win32 Disk Imager

Open Win32 Disk Imager, load the .img file unzipped in previous step and select your SD card drive letter. Click on Write to install FluiddPi on the SD card. This process will take a few minutes, depending on the speed of your SD card.

After the Fluidd image has been flashed, we need to edit the Wi-Fi credentials to auto-connect. You can skip this step if you don’t use a wireless setup.

Set your Wi-Fi credentials

In order to auto-connect the Raspberry Pi to Wi-Fi, we need to edit a file on the SD Card and insert the Wi-Fi credentials.

In your explorer window, navigate to the boot partition, and open the fluiddpi-wpa-supplicant.txt file in Notepad / Notepad++ (don’t use other file editors).

In this file, we need to uncomment line 27,28,29 and 30 then enter the Wi-Fi credentials. To do that, remove the “ # ” character in the front of the line.
Next, enter your Wi-Fi name and password.

In this example, my Wi-Fi is named “MyHomeNetwork” and the password is “SuperS3cretP@ssword

This is how the file looks before entering the Wi-Fi credentials:

This is how the file should look after you entered your Wi-Fi credentials:

Now save the file, and remove the SD Card. Insert it into your Raspberry Pi then start it up. In a few minutes, FluiddPi will boot up and you will be able to access the web interface. If this hyperlink doesn’t open the Mainsail OS web interface for you, find the IP address of your Raspberry Pi.

Find the IP of your FluiddPi Web Interface

In order to connect to your FluiddPi web interface, you first need to find the IP address your Raspberry Pi received from the DHCP server.

Press Windows Key + R at the same time to open Run. Type cmd.exe then press Enter to open Command Prompt.

Open Command Prompt

In the Command Prompt window, type ping fluidd.local -4 and press enter. This will return the IP of your Raspberry Pi.

Install KIAUH

Next step would be to install KIAUH which stands for Klipper Installation And Update Helper. It’s an excellent tool which will make the whole Klipper installation process much easier.

To install KIAUH, we fist need to connect via SSH to the Raspberry Pi.

Connect via SSH

Download Putty , enter the IP of your Raspberry Pi then click Open

In the Login prompt, you need to enter the credentials for FluiddPi. The default user is pi and the password is raspberry. Please note that the password will not be shown when typing.

Install KIAUH

Clone the git repository for KIAUH with the following command

git clone https://github.com/th33xitus/kiauh.git

After the cloning process is complete, navigate to the kiauh folder

cd kiauh

Set the proper permissions for all the files in the kiauh scripts folder

chmod +x kiauh.sh scripts/*

Finally, run the kiauh.sh installation script

./kiauh.sh

The KIAUH GUI will show up, where you can choose to install different packages and services and it’s also possible to update your services. You can use your keyboard to enter your selection.

Wrapping up

With FluiddPi now installed and updated, you can go ahead and upload your configuration file then start the calibration process. You can find configuration files for a few of my printers in the Klipper section of the website.

  1. The git clone for the KIAUH isn’t working for me. Is there a new one I can use? Or do I even have to use KIAUH?

  2. Hello, I am getting a “An error occured when attempting to lock the volume: Error 5: Access is denied” whenever I try to write the fluiddPi onto the SD card

  3. I think you need to add, add printer with the IP address through fluid settings menu as when I installed it the fluid screen overlay was not connecting to Moonracker it was just saying force restart.

  4. I thought it was recommended not to use KIAUH anymore with update built into Fluidd and Mainsail.

  5. Quick questions:
    – Would you rather use Mainsail or FluidPi with Klipper ?
    – Will you propose a Klipper installation tutorial for the Flsun Q5 ?
    Thanks

  6. Thanks for creating these guides. They have been tremendously helpful since I got my Artillery Genius last year.

    I just have one quick questions. What firmware and OS would you recommend using on the Pi with the Artillery Genius? I’m a bit lost with so many options out there.
