## What it is
Klipper is open-source firmware for 3D printers that combines a general-purpose computer (like a Raspberry Pi) with one or more micro-controllers to achieve high print quality and speed. It offloads complex computation to the host computer while micro-controllers handle real-time motor and sensor control.

## Use cases
- control a 3D printer with better speed and precision than stock firmware
- run a 3D printer from a Raspberry Pi host
- get high-step-rate motion control for printers
- tune printer kinematics like pressure advance and input shaping
- replace Marlin firmware on a custom printer build
- manage multiple micro-controllers from one host

## When to choose
- you want faster, higher-quality 3D printing than stock firmware allows
- you have a host computer (e.g. Raspberry Pi) to pair with your printer board
- you want advanced features like input shaping and pressure advance
- you want an actively maintained, well-documented firmware

## When to avoid
- you have no host computer and need a standalone firmware
- you need a simple plug-and-play setup with minimal configuration
- your printer board has very limited connectivity to a host

## Facets
- artifact type: application
