Unsupported geometry for 2D Open Pocket detection!

[info]

Hi all!

I hope one of you can help me out. 
I am running into an error when creating a cutting path for the CNC mill. I have created and cut multiple files already, but this is the first time I see an error like this.

In the first screenshot, you will see the pocket (selected) that I want to mill. It is open on one side. The second screenshot shows the difference in height. I can't believe this is shape is not possible to make, I don't see why it is not possible for the mill the preform. 

Hopefully some of you is a true genius! Looking forward to your reply!

Hi,

maybe 2 D Contour is a better choice?

Thanks for your reply. A 2D contour will cut through the whole plate right?
It should only be 6mm deep.

Cheers!

Hi,

please share the f3d file

What have you selected, a face? It looks like the pocket is actually open on 2 sides, not sure if that is the problem. Don't be scared to use the 3d pockets, quite often they will produce a more efficient toolpath and they are no more difficult to use and set up.

Hi!

Here is the file. As you can see, the model is called "voor" (front in Dutch). I could only download it in .f3z hope that's oke!

Thanks for your replies and help!

Please break the links of the pasted parts, then you can upload them as f3d

Hi Gunter,

Here is the file! Thanks

Changing the Extension method to closest boundary produces a toolpath. Think the problem is down to the pocket being open on 2 sides.

Also you might want to put the pocket at the end of the setup to reduce plunges into the stock. It doesn't get rid of all the plunges into the stock but at least they are not full cutter diameter.
