## What it is
Smoothieware is a modular, open-source G-code interpreter and CNC controller firmware written in object-oriented C++ for 32-bit controller boards like the SmoothieBoard. It drives 3D printers, laser cutters, CNC mills, and pick-and-place machines via USB, Ethernet, or SD card.

## Use cases
- control a 3D printer with open-source firmware
- run a CNC mill from G-code files
- drive a laser cutter with LightBurn or G-code
- set up a pick-and-place machine
- migrate from GRBL or Marlin firmware
- support delta, CoreXY, HBot, or SCARA kinematics

## When to choose
- you use a SmoothieBoard or compatible 32-bit controller
- you need one firmware for 3D printing, laser, and CNC use
- you want a modular, hacker-friendly firmware you can extend with custom modules

## When to avoid
- your hardware is AVR-based and only runs Marlin or GRBL
- you need a large ecosystem of community plugins and vendor support
- you want firmware with active daily development on modern boards

## Facets
- artifact type: application
- maturity: active
- function: interpreter, embedded, parser
- domain: embedded-systems, hardware, robotics
- platform: embedded, cpp
- tags: gcode, cnc, 3d-printing, firmware, laser-cutting, motion-control, smoothieboard, automation, linux
