Rapid Collisions in Adaptive Clearing

I am using Fusion360 for milling wood pieces - the pieces are somewhat irregular and modeled in Rhino.  I am having a hard time eliminating rapid collisions with stock on the adaptive clearing toolpaths.  I have searched the forums and found ways to reduce, but not eliminate these collisions.  It generally seems it would work if the path would just take smaller passes, but I don't know how to force that.  Alternatively, is there an alternative toolpath to use first to clear the way for adaptive?  This is coming up repeatedly for me - one example is in the first adaptive pass of setup2 in the attached.  https://a360.co/45uzLGM

We can't see anything from that link.
Ensure you are properly defining the Stock Contours and everything should be ok. Use 3D adaptive when possible.

Would you be able to share your Fusion file here?

Thanks very much - does this attachment work?  I am using 3D adaptive - are stock contours relevant for that?  I'm new so not sure how they fit in.  Thanks!

Yes - thank you - here it is

I posted a little earlier about rapid collisions on a 3d adaptive toolpath.  I am reposting with some screenshots and the file to give a little more information - one screenshot shows where I am getting the collision, and one shows the piece in rhino.  (This piece is relatively flat, so I just have one collision.  I have had more collisions I have not been able to resolve with pieces that angle more sharply into the stock.)  Thanks for any advice!

I would start with a 2D Contour (with Ramp and Tabs turned on):

We can then make some tweaks to the (2x) 3D Adaptive toolpaths and end up with only one small collision:

If it's the same issues as the prior thread you started, it would be best to keep them in one thread

thanks so much - I really appreciate it.  What are the types of tweaks that can help with these collisions?  I have had greater numbers in other files.

The 2D Contour to clear around the outside helped a great deal. After that, I reduced the Max Stay Down and also changed it to Full Retraction instead of Minimum.
