Mike nailed it [as usual]. Issue was, had tip side angle of the ballnose at 15, changed it to 5 per his suggestion and the ridge disappeared.
15 was just a default, never noticed any issues with anything before so never thought about changing it, and would not have known the side angle if I did. Odd thing is, this computer I usually hash things out, experiment and do things that take time so am not concerned about toolpaths, I take the project, load it in my garage computer and thats where I do the fine tuning and run the toolpaths - On that computer, did not notice the ridge in the preview, and angle was the same. Somethings got to be different, but anyways Mike thanks for solving this annoying issue.
