Klipper is an open-source firmware for 3D printers that enhances their performance and capabilities. It works by offloading complex calculations from the printer's control board to a more powerful computer, often a Raspberry Pi. This allows for faster processing and improved print quality. The firmware supports various 3D printer models and can be customized to suit specific needs. Klipper also features advanced motion planning algorithms, enabling smoother movements and higher speeds. Users can easily configure settings through a web interface, making it accessible for both beginners and experienced users.
