Too Many Passes

[chrisCFHNJ]

I can't figure out how to make a 3d pocket operation do it all in one pass.

Hmm, curious. I don't think I've ever had need to use the 3D Pocket toolpath, but I'd expect to see something different from what you're getting.

As a quick solution, you can set the Top Height and Bottom Height to the surface you're trying to reach:

Thank you for the reply. However, I am trying to set this up so I can use the same template and have it automatically create the toolpath for various depths of dados. It will be done on full sheets of nested parts. So although this solution would work, I would have to set a cut for each height of dado in the model and select faces of each.

You are a bit screwed in trying to automate this I think...  The reason I could see for the 3 depths, is that you have "flat area detection" turned on.  With that, rotate your model a bit, and you will see that the 2 extra passes correspond to the shallower grooves that are in the plate.  This is unfortunate, because you are not intending to machine those 2 grooves with that same tool since it does not fit.  But, Fusion is not clever enough to see that, and it generates a path for those depths.

Now if you turn this option off, it won't cut anything, because the bottom height is set to the model bottom, and at model bottom there is no flat face to machine.  So you need this option ON, but with this option ON, it will generate a path on all the depths, which is why I think you are a bit screwed, you can't really automate it it seems to me.  You will be forced to pick the floor as the bottom height.

I can't think of a way to make this automation possible for you.  Maybe @engineguy can think of something, he's pretty handy with this kind of stuff.  Anyways, to me, Fusion is lacking a bit here.

@DarthBane55   Nope, not got any more on this except that it does seem to work with the Bottom Height set to "Model Bottom" and as you correctly point out with the "Flat Detection" turned OFF and "Stock Contours set for the areas required, just more to do 🙂

FWIW for the task shown maybe a 2D Pocket strategy might be better as it is will just work to what it is set to, also, agreed, can`t see any easy way to Template it 😞 😞

Thanks for your help guys. It is nice to know what I am dealing with. Although it isn't ideal, I noticed that most of our dados are either .14 deep or .51 deep. So I made two separate strategies with different Z height ranges, and that works if I put them in the right order.

Still, this is something that should be fixed!

I know this is an old thread, but...

I am facing this exact issue. I have both shallow dados and deeper rabbets on a bunch of parts that are nested into full sheets of plywood. In trying to use 3D Pocket toolpath on the rabbets, it generates multiple depths just like the OG's issue.

I've tried to use 2D Pocket, but since it sees the rabbets as open pockets, I can't get it to ramp into the cut (which I need because the parts are in the middle of a full sheet).

Is there really no way to force 2D Pocket to ramp into an open pocket?
