Yes, and I even found it did it right a couple times. I also found it
doing some VERY strange things, so I have never trusted it. I tried some
real simple test patterns, like a square and a circle.

Are there some rules about how to start and stop the cutter comp? It
seemed like I had to make an offset move first to get away form the part
edge, then turned on cutter comp and it ran around a square OK.

Suppose I had a simple square like this:
G00 X0 Y0
G01 X1
G01 Y1
G01 X0
G01 Y0

That I wanted to do with a 1/2" mill, around the outside, leaving a
finished 1" square. What gcodes should I add to make this?
