Parmi les outils de pilotage GRBL, il existe CNC.JS

Concernant mon utilisation, il présente un gros intérêt : fournir une interface de contrôle via serveur web, permettant de piloter le tout depuis une machine qui ne devra pas être physiquement connectée à la CNC.

En conséquence, le serveur cncjs est installé sur un raspberry pi 3B+, lui-même connecté en wifi à la maison.

Ensuite, depuis n'importe quel laptop ou tablette, également en wifi à la maison, je peux me connecter à cette page : http://cncjs.local

Suivre les instructions présentées ici : https://cnc.js.org/docs/rpi-setup-guide/

Les éléments de configuration qui suivent servent également de backup en cas de recréation d'un cncjs.
