I think G71 will not use Tool Compensation. But I think the finish pass G70 does. Somewhere I read that you have to make U and W in the G71 a bit bigger than your tool nose radius so there will be something to clean up with the G70.
You can check it in graphics by stepping through.
Another thing that will give trouble is if you don't have the correct Tip # based on the tool position. There is a section in the manual explaining it.
An open mind is a virtue...so long as all the common sense has not leaked out.
