Use Single Block.
Zoom the screen in; F2 then Page Down followed by Write.
Center the view; F2 then use the Cursor Keys, Up, Down, Left, Right, followed by Write.
Then bring up the Machine Position display; F3 one or more times.
The Graphics run very fast and because cycles such as G71 do not stop at the end of the move but jump back to the start point you will miss the furthest point. You can catch this by turning Single Block off for these cycles then the instant the display starts moving on the cycle push the Single Block key; this will cause the display to stop at the end of the cut.
Another way is to zoom in very tight to the end of the cut and just watch the display closely.
An open mind is a virtue...so long as all the common sense has not leaked out.
