RE: Great deal on rotary encoders

Oh how right you are Dan. I got home early tonight and just tried setting
the program to 40,000 (the value for a 10 TPI lead screw) and the readout
you get is definitely buggered up. It indicates about 1.5 x the correct
value.

So, until Tom updates the program it looks as if these encoders will only be
of value for people with 5 TPI or less lead screws.
