Can't set entry point on stock corner (or seemingly anywhere) for 2d pocket operation

[jrTBEJE]

See screen captures. I have stock defined, when i select stock contours in pocket operation, it shows up orange. I then open the  "Linking | positions | entry positions" and click to try and select the origin of the stock and i can't figure it out.

In general i am trying to set the starting point of this operation to a known position on the stock and be able to anchor the stock to the table at the right place under the bit. I have a GRBL POST processing and am using a home built machine and UGS software to send the NC to the machine. I've used fusion to output the POST NC to it. It works and does the pocketing operation fine with no stock and no bit, but i can't figure out how to set the start point to a known point on my stock and the stock to a known point under the bit so its in the right spot.

The forum users could probably get a better handle on this is you attached the model.  You would get better response probably if you place your forum question and model on the Manufacturing Forum.
