Klipper Firmware
Klipper is an open-source 3D printer firmware ecosystem that separates motion planning from micro-controller execution. It runs high-precision kinematic algorithms, Web UIs (Mainsail/Fluidd), and calibration routines on a powerful microcomputer while using lightweight microcontrollers purely for low-level step timing.
Architecture: Host Computer vs Microcontroller
Unlike traditional 8-bit or 32-bit standalone firmware, Klipper runs its heavy mathematical calculations on a Raspberry Pi or Linux host, sending pre-calculated step queues to the printer’s control board via high-speed USB/UART.
Advanced Features & Dynamic Calibration
Klipper pioneered active input shaping, smooth pressure advance, adaptive bed mesh probing, dynamic macro scripting, and seamless remote web browser management via Mainsail and Fluidd.
The Engine Behind Modern High-Speed Printing
Klipper is the foundational software platform powering DIY community flagships like Voron Design and RatRig, and inspired the proprietary operating systems of next-generation commercial printers.
