Ric,
You don't say where the cutter is ending up, but if it is ending at +.25, then it sounds like your controller is set to do relative rather than absolute movement.
In other words, in relative movement, you are telling it to move up .5" and then down -.25" ending up at positive .25".
In absolute movement, it would move up to .5" and then back down to -.25" which is what you indicate that you want.
I could be way off base, but it is a thought.
