Shapeoko CNC router Electronics Upgrade - Part 2: Finishing the Enclosure and Electronics Mounting Parts

Preparing the Enclosure for the Electronics

I had to print three parts to get everything to fit snugly inside my new enclosure.  First, I needed a mount for my Raspberry Pi.  I found an appropriate one on Thingiverse:  http://www.thingiverse.com/thing:37889 .

Next I needed an Arduino Uno/grbl mount:  http://www.thingiverse.com/thing:33327.  Finally, I needed a fan grille, but I could not find any out there that I could download and print directly.  I then came across this wonderful parametric fan grille that one could download, configure and print, brilliantly written by John Ridley a couple of years ago.

I downloaded the scad file, opened it using OpenSCAD"The Programmers Solid 3D CAD Modeller" (free).  All I had to do was take some measurements with my caliper, enter all the parameters the program required and, voila! a perfect fan grille, perfectly sized, ready to be printed:


In a pleasant surprise, printing went off without a hitch.  Here are the printed parts:


The next step was to mount the emergency-stop button, fan and fan grille to the top of the box:



I then used screws and trapped nuts to put the rest of the enclosure together.


With the enclosure and mounting parts complete, I am ready for the next step:  Turn the Raspberry Pi into a dedicated gcode sender that can be wirelessly remote-controlled from any computer or tablet in the house.

  2. This is some pretty good stuff that is quite easy to learn. I like how the printed products turned out. Such fine detail. :)

  3. So I have no idea what exactly cnc routers are. But my brother told me to look them up, and I'm not so sure what I'm supposed to look out or figure out.
