Tool change Z probing problem

New to the game. Trying to machine a software provided relief or a down loaded .stl model using Carveco software, clearing tool seems to do its job every time how ever after tool change and probe 1/6" ball end cuts air, every time .110" high.Used 2 different computers and software sets same result. Any ideas? Thanks

what firmware are you running?

1.0.5 And Thanks for getting back to me on this.

Next piece of the puzzle, I updated the firmware on the off chance that would resolve the problem. Same results, after tool change and probe still cuts air. The carveco software generates the tool paths for the roughing tool and the finishing tool at the same time, so instead of saving them both as one file I saved and ran the separately, and the cut was near perfect. It appears that what ever is happening occurs at the tool change and probe when I am prompted to change the tool and probe. Again any ideas. Thanks
