A web-based interface for CNC milling controller running Grbl or TinyG2. It runs on an Raspberry Pi or a laptop computer that you have Node.js installed, connecting to the Arduino over a serial connection using a USB serial port, a Bluetooth serial module, or a Serial-to-WiFi module like XBee or USR-WIFI232-T.

• Supported CNC controllers
  • Grbl v0.9 or later
  • TinyG2 v0.97 or later
• Desktop App for Linux, Mac OS X, and Windows
• 3D Visualizer
• Allows multiple HTTP connections at the same serial port
• Responsive view for small screen display with device width less than 720px
  • Safari on an iPhone 5S
    
  
• Widget Management
• TinyWeb Console for 320x240 LCD Display
• Keyboard Shortcuts
• Contour ShuttleXpress
• I18n Ready
• Z-Probing

Node.js v4 or higher is recommended. You can install Node Version Manager to manage multiple Node.js versions. If you have git installed, just clone the nvm repo, and check out the latest version:

$ git clone https://github.com/creationix/nvm.git ~/.nvm
$ cd ~/.nvm
$ git checkout `git describe --abbrev=0 --tags`
$ cd ..
$ . ~/.nvm/nvm.sh
$ nvm install 4

Add these lines to your ~/.bash_profile, ~/.bashrc, or ~/.profile file to have it automatically sourced upon login:

export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && . "$NVM_DIR/nvm.sh" # This loads nvm

If you're using Node.js v4 or earlier versions, it's recommended that you use npm v3 to install packages. To upgrade, run:

npm install npm@latest -g

If you're not using Node Version Manager, make sure you have prefix=~/.npm in ~/.npmrc to install global packages without sudo. For example:

$ echo "prefix=~/.npm" >> ~/.npmrc
$ cat ~/.npmrc
prefix=~/.npm

Install cncjs without sudo, or the serialport module may not install correctly on some platforms like Raspberry Pi.

$ npm install -g cncjs

It's recommended that you run Raspbian Jessie on the RPi2 or RPi3. For Raspbian Wheezy, be sure to install gcc/g++ 4.8 before npm install.

Check out wiki for other installation methods.

Run npm update -g cncjs to upgrade to a newer version. To determine the version, use cnc -V.

Run cnc or ~/.npm/bin/cnc to start the server, and visit http://yourhostname:8000/ to view the web interface:

$ cnc

Run cnc with -h for detailed usage:

$ cnc -h

  Usage: cnc [options]
  
  Options:

    -h, --help                  output usage information
    -V, --version               output the version number
    -p, --port                  set listen port (default: 8000)
    -l, --host                  set listen address or hostname (default: 0.0.0.0)
    -b, --backlog               set listen backlog (default: 511)
    -c, --config <filename>     set config file (default: ~/.cncrc)
    -v, --verbose               increase the verbosity level
    -m, --mount [<url>:]<path>  set the mount point for serving static files (default: /static:static)

If you need view detailed logs for troubleshooting, you can run the server in debug mode.

$ cnc -vv

There are several *.gcode files in the examples directory. You can use the GCode widget to load a GCode file and make a trial run.

If you don't have a CAM software, try using jscut to create G-Code from *.svg. It's a simple CAM package that runs in the browser.

Check out a live demo at http://jscut.org/jscut.html.
