WCS Origin question

[LibertyMachine]

I have a rather particular situation. I might be doing some CAM subcontracting work for a customer. They have a particular preference when it comes to their "Z zero".  For the standard vertical mill job, they prefer "Z zero" to be 1" above the part (I program with Z zero as the top of the part)
Now, the question is this: What is the easiest method? Right off the bat, I'm inclined to just make my stock 1" thicker than the model. The "problem" with this is that I end up with a decent amount of collisions as I'm simulating out the job. I'd prefer to have that not be the case, for obvious reasons.

The second option I'm thinking is to get my post podified to automatically put in that 1" difference, but that's not something I'm entirely convinced I can resolve on my own, considering how hacked up my post has become

Thoughts, comments?

You could create an offset plane and project a corner point on to it or draw a point and use dimensions to get it it the right place.

Then select in the setup.

Yeah, I could do that too, I didn't think of that. That might be the easiest solution

Thanks!

Edit: Just as a mental excersise though; I'm assuming having a post modifed to calculate out the extra 1" difference is actually possible. Just curious what that would entail...

As a note: not that weird, they probably touch off with a 1-2-3 block and don't compensate in order to keep from fat fingering errors.

I use a 2" height setter and use a datum shift on the first line of the program, I have it commented out and just remove the asterisk if I need it.

That's exactly what they do. It's just weird to look at a program that has G0 Z-.950 as it's first move, before it even goes deeper to cut.
