Blending a circular groove without crashing.

Learning Fusion and I want to machine a boss on a plate. I want to start at the boss as if the finished plate were very thin. I am using Contour2D. to mill several circular slots. When I do this, the tool path swings out to blend at the bottom of the slot. I want to avoid this. I would like to stay on the milling path and blend up to avoid tool stop mark. See drawing. How do I do this? Note my tool is designed for shallow cuts only.

If you go to the linking Tab and turn off the lead out, the tool will finish the cut and then retract straight up:

You also have the option of turning off "Same as Lead-in" and then you can modify the lead out paramters as you see fit.:

If I am making an oring groove that is the same width as my tool, 2DContour will not spiral down , cover the bottom and spiral out at least some to avoid tool stop mark. Is that correct?

Here is another thought. If I need to mill cut a shape out of 1/2" plate. I use 2DContour to cut the shape by spiraling to the bottom. I lift out like you said. no problem. The cut is ugly. I offset by 0.005"  and repeat but with a faster helix to get  a clean cut. How do I get out without making a tool mark? I use spiral in/out a lot if I have a two flute tool that has two small blemishes at the same depth of cut to avoid the blemish mark by the tool.

Try using "finishing overlap"
