@Paul_Frederick I just like to optimize and simplify my workflow. Done something similar for 3D printing. Which resulted in a small piece of free software called Cura.
@Kyle_Kerr thanks, totally forgot about there being stuff on milling on the reprap wiki. Good starting point 
@Daid_Braam If I wanted to simplify my workflow I could have bought this board fully assembled for about $1.50. With free shipping too!
