2D Pocket not machining all of the pocket

[cadTPLWJ]

I have selected the bottom contour of the slot for 2D pocket machining, but only part of it gets milled. (At least in the simulation)

What is wrong with my design? Design file is attached, dont know if CAM setup is included in the f3d file.

I think the problem has to do with how the model was made.  I went back and made that slot a cut feature from the lower face instead of an addition from the bottom as you had it.  Now that pocket (and a 2d contour that I added) work fine.

Yes, that fixes it.

I think that you selected the top contour of the grove and defined bottom height from that contour made the difference.

If I change to the bottom contour in your version and define heights from there, the problem reappears.Maybe it is wrong to select the bottom of the pocket?

Im not sure why it is the way it is....you should be able to pick either contour and have it work fine with the correct hights.

something is very wrong with that bottom chain.  Im not sure what it is yet...but its related.
