====== Install CNCJS ======
**Raspberry pi** \\
Setup a fresh install of raspian on a raspberry pi.  Enable ssh, vnc, etc. as usual.  

**Download cncjs. ** \\
Note [[https://www.npmjs.com/package/cncjs|this site]] appears to have the latest code and NOT the intuitively named https://cnc.js.org/. 
 
**Install cncjs**\\
Follow the directions on https://www.npmjs.com/package/cncjs.  

**Setup cncjs to autostart** \\
<code>mkdir ~/.config/autostart</code> 
<code>nano cncjs_autostart.desktop</code>
and enter the following lines into the desktop file.
<code>
[Desktop Entry]
Type=Application
Name=cncjs_autostart
Exec=sudo cncjs -p 80
</code>
This should allow the code to autostart.  Note that sudo is required to use a non-default port (default = 8000).  Note that 80 is the default html port (which I like because it makes connecting to cncjs easier).

====== Install grbl ======
TODO.  complete this section.  

**Install grbl on your arduino (TODO add steps) inside of your raspberry pi.**  

**Log into your pi with VNC and install arduino IDE.**

**Install the grbl library**

**Upload to the arduino**


**log into cncjs**
Open your browser, enter <ip address>, and cncjs should load.  Make sure you can connect to grbl on your arduino.  

**Make sure basic functions work**

If the spindle enable pins aren't working, comment out the line #define VARIABLE_SPINDLE inside Inside config.h.  (inside the grbl library).  Note that M3 or M4 is the gcode to enable the spindle and M5 disables the spindle.  Apparently, there is a mixup in pins 11 and 12 somewhere for some shields or with the Uno.  



====== Setup CNCJS and grbl ======
Next, we start tweaking the grbl settings to work with cncjs.
