Jerry Burke had a neat idea over at the 'Zone. He used a USB microscope mounted on the router support to view a good metal straightedge, which gives good distance measures (good to 0.005"). If you combine this with accurate grid paper it can give very good (x,y) measurements. Two good measurements [ set the origin as (0,0), a point along Y motion, a point along X motion] gives very good angles. here is the XL sheet I used to do the math, rename from txt to xlsx
The image is an example of the USB microscope image. The lines on the paper are 0.008" wide.
