Klipper is an open-source firmware that significantly enhances the performance and control capabilities of FDM (Fused Deposition Modeling) 3D printers. Compared to traditional firmwares like Marlin, Klipper offloads the computational load from the printer's control board to a more powerful processor (typically a Raspberry Pi), enabling faster and more precise motion control.
What is Klipper? What are its Advantages over Marlin?
Marlin is the default firmware for many 3D printers and is widely used. However, Marlin's operation on control boards with limited processing power can lead to performance issues, especially with complex models and at high speeds. Klipper solves this problem by delegating the computational load to a more powerful processor, such as a Raspberry Pi. This allows for:
- Higher printing speeds can be achieved.
- More precise motion control is provided.
- Advanced features like Input Shaper can be used.
- Easy configuration and control through a web interface are offered.
Required Hardware: Raspberry Pi and Others
For Klipper installation, you will first need the following hardware:
- Raspberry Pi (Model 3B or newer): This will host Klipper's main processor.
- MicroSD Card (at least 16GB): This will host the Raspberry Pi's operating system (MainsailOS or FluiddPi).
- Power Supply: A power supply that provides sufficient current for the Raspberry Pi.
- USB Cable: To establish a connection between the Raspberry Pi and the 3D printer's control board.
Alternatively, single-board computers like Orange Pi or similar can be used instead of a Raspberry Pi, but Raspberry Pi is more commonly preferred due to its widespread availability and community support.
Easy Installation with KIAUH
To simplify Klipper installation, a tool called KIAUH (Klipper Installation And Update Helper) can be used. KIAUH is a script that automates the installation and updating of Klipper, Moonraker, Mainsail/Fluidd, and other necessary components.
To install KIAUH, connect to your Raspberry Pi via SSH and run the following commands:
sudo apt update
sudo apt install git
git clone https://github.com/th33xitus/kiauh.git
cd kiauh
./kiauh.sh
Complete the installation by selecting Klipper, Moonraker, and your preferred web interface (Mainsail or Fluidd) from the KIAUH menu.
MainsailOS and FluiddPi: Web Interface Choice
MainsailOS and FluiddPi are web interfaces used to manage Klipper. Both offer similar functionality, differing in their user interface and some additional features. You can choose one based on your needs and preferences.
- MainsailOS: Offers a more comprehensive interface and provides more customization options.
- FluiddPi: Has a simpler and faster interface, and may perform better on Raspberry Pi models with lower processing power.
Printer.cfg Configuration
One of the most crucial files for Klipper is the printer.cfg file. This file defines your printer's hardware specifications, motor drivers, sensors, and other settings. Correct configuration is critical for Klipper to function properly.
To create the printer.cfg file, you first need to find a sample configuration file suitable for your printer model. You can find this file on the Klipper website or from 3D printer communities. You will need to adapt the found file to your specific printer. For example, you must correctly define your motor drivers, limit switches, and nozzle temperature sensor.
After completing the basic configuration, it is recommended to perform the following advanced calibrations:
Input Shaper Calibration
Input Shaper reduces printer vibrations.
