I am doing side work with a local small shop. I am working on getting a Miyano BNC 34T programmed and running a simple part. This machine is unfamiliar to me and there in no one there that knows anything about it. My issue is end of the part is turned down to .1065 the first .405 so I am trying to turn that close to the collet and then bump it out to finish the rest of the part. When it goes to call up the tool to bump it our I get a 507 p/s alarm which I know it an overtravel alarm. I have tried changing the tool offset (T72) I have tried changing the B approach dimension. I am kinda stuck. Any help would be greatly appreciated.

Here is the program
