NOTE: Google ended support for Chrome apps in 2022, so this application does not work anymore. Please see python based GeeSaw Feeder v2 for an alternative approach to similar functionality.
gcode-sender is a chrome application capable of sending gcode commands to a USB gcode intrepreter (hobby CNC machines / 3D printers). It was developed by sir-buckyball.
This implementation, gee-saw-feeder (GeeSaw feeder), is a superficially retouched fork of that very solid app, which adapts it to a 2D (XY-only) gcode sender, matching the reqirements of a prototype grbl-based CNC scroll-saw machine called 'GeeSaw'.
The easiest way to install the gcode-sender chrome extension is to download it from the Chrome Web Store (https://chrome.google.com/webstore/detail/gcode-sender/ngncibnakmabjlfpadjagnbdjbhoelom).
If you want to develop for it, you can load the 'src' directory as an unpacked extension. By going to <chrome://extensions/>, ensure 'developer mode' is checked and you should see a program-starter (desktop configuration file) to load it from your local file system, by giving a unique 32-chararacter long reference-name as argument to google-chrome.
Unfortunately, this also means that you cannot simply download the source files from this repository and immediately launch it, since the necessary, randomly generated reference-name string for google-chrome is lacking. It seems the preferred procedure is to download a copy of the 'src' directory from the Chrome Web Store, as described above, and then edit or swap out files as desired.
