Post not correct on Z height at machine when using (PRE NGC) haas with a axis

[lwagner2020]

Hello. I'm having an issue when I post the CAM program. The contouring operation and the 1st 2d pocket operation works fine. When the rotary indexes to the next position the post has the Z height at about 1/2" too high. The CAM toolpath looks fine and when I click on view tool path all the Z heights are negative as they should be.

Unless you have a modified post processor, you will need to set your WCS to center of rotation. With it set to the top, all your indexed Z values are going to be incorrect.
