3d contour won't do undercutting, even with multi axis

Hello

 

I stuck with this problem. I don't have alot of experience with fusion 5-axis simultaneus opreations, but i need to find a way to cut this undercut in a spiral / constans-z way, but no matter which operation i choose, it seems like it won't go in under the overhang, even though i have seen youtube videos showing simultaneos undercutting being done. 

 

Also the videos i have seen of steep and shallow to undercutting, there was a undercutting checkbox, but this seems to have been removed??

 

I have tried with both 2mm, 3mm, 4mm none of works.

 

It's a part for an customer, so i can't share the part, but i will do my best to show the settings.
