As I have stated in the past there is value in learning. I found
the challenge of hooking up the mechanical components, wiring the
unit, building the controller and getting it all working with the
CAD, CAM and controller software configured and working to be a
sufficent challenge.

I like to see progress and perhaps I am impatient enough that I
don't want to work down at the component level unless absolutely
forced to do so. Even with buying my motor controllers, breakout
cards and controller software, it still took me almost a year of
weekends and spare time to complete my router/plasma table. I
learned a lot along the way without building all of it piece by
piece.

We will help you along with whatever you want to do. Post your
schematics and we will give you suggestions.
