How to Install Klipper Using KIAUH - Klipper Install and Update Helper

ยท 11 min read


Klipper is quickly becoming the de-facto choice for fast 3D printing. 3D printer manufacturers such as Voron and Prusa3D have contributed to its popularity by using firmware in their machines. And as Klipper's completely open-source and free-to-use, you can install it virtually on any 3D printer, old or new.

In this article, we'll go over the installation process of setting up the Klipper firmware using the Klipper Installation And Update Helper (KIAUH). It's an effortless and interesting way to install Klipper on your 3D printer.

Let's start Klipping!

What is Klipper Firmware and why do you want it?โ€‹

Klipperwas first released in 2016 by Kevin O'Connor as a 3D printer firmware for executing high-speed 3D printing. It controls your 3D printer's movements and various functionalities and acts as a bridge between your machine's software and hardware components.

Typically, 3D printers rely solely on their microcontrollers to compute and execute all printing tasks. It's a demanding role, and 8-bit controllers cannot manage the various functions efficiently, thus limiting their print speeds and delivering sub-par print quality. However, Klipper utilizes a supplementary computing device (typically a Raspberry Pi) in addition to the printer's microcontroller.

As Klipper uses an additional processing device, it can divide the printing duties between the Raspberry Pi and your printer's microcontroller. All the computations are done on the Pi, which is much faster and more powerful, and passed on to the controller. The controller's sole job is to pass these commands to the printer's hardware.

This configuration gives you access to various features such as smooth pressure advance, input shaping, high stepping rates, and multi-controller support. Besides these features, you can access all of Klipper's functionalities using a web interface with either Fluidd or Mainsail OS.

What is KIAUH, the Klipper Install and Update Helper, and why would you want to use it?โ€‹

KIAUH is a firmware tool developed by th33xitus that enables you to install, configure, and update your Klipper firmware easily. It gives you an easy-to-use interface for installing the Klipper firmware and automates a considerable chunk of manual input.

It lets you back up your Klipper's configuration within a few steps and access every aspect of Klipper right from your Raspberry Pi. You can add the KlipperScreen, install Mainsail OS and Fluidd simultaneously, and remove any unnecessary files from the KIAUH interface.

Basically, KIAUH gives you an easy entry into the backdoor of the Klipper's firmware. It makes the installation and configuration process more straightforward and will come in handy if you're constantly tinkering with Klipper and your 3D printer.

Various methods for Installing Klipperโ€‹

KIAUH is not the only method/tool for installing Klipper; however, it's also not the most standard procedure. You can install it with the help of Mainsail and Fluidd software or execute a manual installation for more control.

If you'd prefer the slightly involved method, you can refer to our guides for installing Klipper with Mainsail and Fluidd web interfaces. These guides will inform you about a somewhat different approach to installing Klipper.

What do you need to set up Klipper with KIAUH?โ€‹

KIAUH itself is a tool that runs on Raspberry Pi's interface. It'd be easier to set up by installing Fluidd or Mainsail OS web interfaces. This procedure will help us to set up Klipper quickly and with minimal error.

Here's a list of things you'll need to set up Klipper with KIAUH.

Now that you're fully equipped with tools and knowledge, we can begin Klipper's installation process.
