Milled hole ended up .005 bigger than the size I programmed on my KMBX-1?

Hi,

I am running my KMBX-1 via conversational programming and today I milled a hole that was supposed to end up 1.125" instead it ended up 1.130"! I have tripple checked all my settings and I can't find any reason why this would happen! My cutter in a true .500 mill and I set .500 as cutter. I put in compensation . I set .5625 as my radius setting for the hole I was milling.

Any idea what I am missing?

Thanks

God bless...
