Hu,
What you have listed is correct. It is the standard haas post cfg.
But I think your problem comes in when you get to the "cycles" box. Let me try to explain.

If you look at use the Haas post, (note you have to select the post, ie haas or shadow, before you use the machine cycles) and select your points then the tool, then clearance, you will get to the cycles box. This is where there is a difference between the two.

The Haas cycles box has only: "retract mode" to check.

The shadow cycles(the one you sent me) has:
Peck dist/z
Dwell /t
Safety......../z (wouldn't this be the Retract plane?)

I tried your shadow post and I get the same results you do.

I think this extra info from the cycles box is what is causing the Heartburn. But that is only a guess. I have messed around with different values in both of the boxes , but I am not able to make things work the way you would like.
