Building a CNC - The start - Conceptual design

I've been cooking this idea for quite a while now.
A brand new CNC.

With Crappy CNC still in the "hospital", I've started to plan a new CNC trying to improve all the previous faults of Crappy.

Better rigidity.
Cheaper materials.
Less axis alignment issues.
Build with accessible tools.

I'm leaning towards a Momus CNC similar design with some dramatic changes.
Here is a partial sketch of Crappy 2. Has you can see the main difference between the Momus and this one is the crossed mount free double arm.

The concept is to keep the counter force that causes frame distortions closer to the milling point.

I'm in the building phase right now. but it's being painfully slow.
More updates coming.
