You can use your LaserGRBL to send G-code command to a Wifi websocket.

This can be usefull if you don't want your Laser Cutter to be in the same room than your computer. As LaserGrbl is not so user friendly with Linux (or Raspbian) on a Raspberry PI, you can use your Raspberry Pi as a remote access from LaserGrbl.

This program send G-code to serial USB. It analys message from LaserGRBL and can execute Python script when G-Code instructions are send from LaserGRBL.
