Following on the CMC Machine post where I tried to understand the flow from
Computer Aided Design (CAD) to
Computer Aided Manufacturing (CAM) and finally to
Computer Numerical Control (CNC) I felt I was in a good space to look at scratch building a Machine. Although it is possible to purchase a kit, its a lot more expensive and I was inspired by Gökmen ALTUNTAŞ to build a CNC Machine with a wood frame.
These are some of the DIY Kits I looked at, the cost was just too high for my pocket!
I thought a good place to start is watch and understand the two part Youtube series, then document the steps and finally cost it. At 600mm by 400mm working bed area I felt this is a pretty good first machine.

Trying to un-pack the videos into steps I can follow.
The base frame is just a rectangle with the 12mm Linear Rail for the
