First a little history.
CNC Construction Set Build 1
Build 1 consisted of several iterations of the early prototype. The plate material used was Corian. The Corian was very easy to cut and drill with standard woodworking tools. Corian can be a little pricey if you cant locate any locally. While I did develop some interchangeable Z carriages, this machine is primarily set up as a plasma CNC.
Shown here it has a floating head IHS and a steel angle cutting fixture.

CNC Construction Set Build 2
Build 2 used PVC as the plate material. While this was very easy to cut and drill, it is not as rigid as the build using the Corian plates. This machine I am currently using for milling and to test my rotary axis.
Shown here, build 2 has many upgrades added that I will eventually be documenting.

In this blog, I will be covering build 3.
Very happy with the build so far, I decided to start a third build, using MDF. Since this plate material is listed in the book I needed to try it out. I will also be doing the advanced electronics option on this build since it will also support CNC operations.
