John S,

Yep you are completely correct on that one. CamBam will pocket a "drill" hole where the end mil is smaller in diameter then the required hole and as you can see it does it in a spiral pattern. Works rather well on the code I use and will drill when the endmill is the same diameter as the hole. Rather interesting code structure on that part. As to why it is stopping I don't know as ran fine for me as well. Could be that the OP is getting a false trigger that is causing the problem. Well have fun folks.
