About:
cncjs is a web-based interface for controlling CNC (Computer Numerical Control) machines. It connects to controllers like Grbl, Marlin, Smoothieware, and TinyG via serial port or network. The tool provides real-time monitoring, G-code editing, and job management capabilities directly from a browser.
Key Features:
  • Web-based UI accessible from any browser
  • Supports multiple controller firmwares (Grbl, Marlin, etc.)
  • Real-time G-code visualizer and workspace viewer
  • Plugin architecture for extending functionality
Use Cases:
  • Controlling DIY CNC routers and 3D printers from a local network
  • Monitoring and managing G-code jobs with visual feedback
Alternatives:
  • Universal G-code Sender (UGS) – UGS is a Java-based desktop app; cncjs offers a more modern, browser-based interface with network access.
