This T-slot toolpath is driving me crazy!!!

[pferrick]

Hi all-

I've been struggling with cutting this T-slot, and no matter how I tweak the settings I can't seem to get the tool to retract outside the part.  It's an adaptive 2D, and I've looked at and (mostly) understood what the appropriate settings do.   I've added and selected an exit point, adjusted the maximum staydown distance, and tried what seems like every permutation of these and other settings.  

I'm obviously not understanding something really important, but I'll be damned if I can figure out what it is!   (This despite the example in the exit-position help bubble being a T-slot toolpath.  Sheesh...if somebody could put me out of my misery I'd greatly appreciate it.)

EDIT:  I have already milled out the center of the slot with an endmill, so as far as I can tell the T-slot cutter should be able to finish it up, if I can get things set up correctly.

Thanks,

Patrick

Does 3D adaptive work? Because otherwise this isnt really what the toolpath + tool combo is meant for. Why not slot out the center, then use the tool as designed?

Thanks!      I neglected to mention that I have already slotted out the center with an endmill.   I will try the 3D adaptive if it's avaliable (I'm using the Educator version of Fusion).

You should just be using 2D Contour for this.

可以用这个策略，但是不建议。
