cncjs
A full-featured web-based interface for CNC controllers running Grbl, Marlin, Smoothieware, or TinyG.
What is cncjs?
CNCjs is a web-based interface for controlling CNC machines and 3D printers that run on firmware like Grbl, Marlin, Smoothieware, or TinyG. It allows users to send G-code commands, visualize toolpaths in 3D, and monitor machine operations from any modern web browser. The project solves the need for a flexible, cross-platform control solution that can be accessed remotely and extended with custom widgets and hardware pendants.
CNC hobbyists, makers, small workshop operators, and educators who use open-source CNC controllers and want a modern, browser-based control interface. It's also suitable for developers interested in extending CNC functionality with custom widgets or integrating with Raspberry Pi and other hardware pendants.
Developers choose CNCjs because it's a free, open-source alternative to proprietary CNC software, offering extensive hardware compatibility, a rich web-based UI, and strong community-driven extensibility. Its ability to run as a self-hosted server and support for multiple simultaneous clients provides flexibility not found in many traditional desktop applications.
