Tom, have you verified that one paper thickness (about 0.004") is the correct spacing between the mounting screws and the encoder disk for proper operation?
I'm asking because this advice seems to conflict with the information given on the manufacturer's web site( http://www.usdigital.com/products/e4p/index.shtml) under the heading "Accessories/Spacer Tool", which indicates a nominal gap between codewheel and encoder base of 0.070" with +/-0.030" tolerance.

I believe in intuition and inspiration. Imagination is more important than knowledge. For knowledge is limited, whereas imagination embraces the entire world, stimulating progress, giving birth to evolution. It is, strictly speaking, a real factor in scientific research.
