I had checked Final Depth before, as it was irritating: it showed "-1" although the value set was 9mm. No matter whether I set it to 9 or left it automatic, it didn't work.
After your post I checked the other parameters and found that Step Down was at 5mm. Changing it to 1mm the path is generated. The problem seems to be, that the first step down already exceeded the final depth.

Brilliant! Thanks for your help.

Glad I could help and glad I found something to remember.

This may be unique to Pocket operations. Profile_Edges does not exhibit the same behavior. I selected the shape of the letters and did a Profiles_Edges operation with the Step Down set to 50 mm. A single path was created at the Final Depth, as it should be.
Probably a deficiency in the Pocket operation.

That's what I thought as well. So I thought that might be simple enough to find and searched the code in order to simply change the internal value of StepDown to something better. Well, searched a while and finally built a simple test case, with the same situation as the logo above:
- Base object's height 10mm
- Pocket ending at 9mm
- create Pocket from Shape
And everything is ok. I will have a third look at the logo, but for now I think Pocket_Shape is ok. It might handle some strange situations better, but I cannot describe these situations yet.

Re: How to Pocket Cut a Logo
I recreated the model from my previous post going a way closer to the op's logo:
- created Part->Cylinder
- created Sketch in XY plane
- turned Sketch 180° around Y axis. Without this step the following extrude cannot be made forward to meet op's situation.
- created draft object from Sketch
- downgraded to get a face
- moved face to z=9
- extruded 1mm forward, direction: normal to face
- subtracted extrude from cylinder
- created Job, leaving everything at default
- created Pocket from shape, leaving everything at default. Inspecting depths showed FinalDepth=-1mm as with op's model.
- Confirmed and path was generated as before
Conclusion: no problem in Path WB.
