Node.js 14 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
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" ] && . "$NVM_DIR/nvm.sh" # This loads nvmOnce installed, you can select Node.js versions with:
nvm install 14
nvm use 14
It's also recommended that you upgrade npm to the latest version. To upgrade, run:
npm install npm@latest -g
Install cncjs as a non-root user, or the serialport module may not install correctly on some platforms like Raspberry Pi.
npm install -g cncjs
If you're going to use sudo or root to install cncjs, you need to specify the --unsafe-perm option to run npm as the root account.
sudo npm install --unsafe-perm -g cncjs
Check out https://github.com/cncjs/cncjs/wiki/Installation for other installation methods.
Run npm install -g cncjs@latest to install the latest version. To determine the version, use cncjs -V.
Run cncjs to start the server, and visit http://yourhostname:8000/ to view the web interface. Pass --help to cncjs for more options.
pi@rpi3$ cncjs -h
Usage: cncjs [options]
Options:
-V, --version output the version number
-p, --port <port> Set listen port (default: 8000)
-H, --host <host> Set listen address or hostname (default: 0.0.0.0)
-b, --backlog <backlog> Set listen backlog (default: 511)
-c, --config <filename> Set config file (default: ~/.cncrc)
-v, --verbose Increase the verbosity level (-v, -vv, -vvv)
-m, --mount <route-path>:<target> Add a mount point for serving static files
-w, --watch-directory <path> Watch a directory for changes
--access-token-lifetime <lifetime> Access token lifetime in seconds or a time span string (default: 30d)
--allow-remote-access Allow remote access to the server (default: false)
--controller <type> Specify CNC controller: Grbl|Marlin|Smoothie|TinyG|g2core (default: '')
-h, --help output usage information
Examples:
$ cncjs -vv
$ cncjs --mount /pendant:/home/pi/tinyweb
$ cncjs --mount /widget:~+/widget --mount /pendant:~/pendant
$ cncjs --mount /widget:https://cncjs.github.io/cncjs-widget-boilerplate/v1/
$ cncjs --watch-directory /home/pi/watch
$ cncjs --access-token-lifetime 60d # e.g. 3600, 30m, 12h, 30d
$ cncjs --allow-remote-access
$ cncjs --controller Grbl
Instead of passing command line options for --watch-directory, --access-token-lifetime, --allow-remote-access, and --controller, you can create a ~/.cncrc file that contains the following configuration in JSON format:
{
"mountPoints": [
{
"route": "/pendant",
"target": "/home/pi/tinyweb"
},
{
"route": "/widget",
"target": "https://cncjs.github.io/cncjs-widget-boilerplate/v1/"
}
],
"watchDirectory": "/path/to/dir",
"accessTokenLifetime": "30d",
"allowRemoteAccess": false,
"controller": ""
}To troubleshoot issues, run:
cncjs -vvv
The configuration file .cncrc contains settings that are equivalent to the cncjs command-line options. The configuration file is stored in user's home directory. To find out the actual location of the home directory, do the following:
-
Linux/Mac
echo $HOME
-
Windows
echo %USERPROFILE%
Check out an example configuration file here.
See #242 (comment) for a detailed explanation.

}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.
