====== CNCJS ======

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

===== Setup sur Raspberry Pi =====

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

===== Configuration =====

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

===== Extensions =====

A réinstaller potentiellement : 
cncjs-kt-ext : autolevel extension
Le script de lancement contient : 
```
#!/bin/bash
cd /home/pi/cncjs-kt-ext

node . --port /dev/ttyUSB0
```

et probablement : 
cncjs-shopfloor-tablet-2.0.0 : pour un accès mobile... (pas convaincu).
