The only additional surface I created was the flat, check-surface to limit the down-travel. But I'm still using 'center' comp. I'll change it to 'tip' and see how it does. I think with the check surfaces, it should be okay.
You're saying it shouldn't need the check surface?
Attached are the two results. It's a verification of only two operations: rough and finish of the surface. You can see how the cutter plunged through the hole in one example. That's what it was doing on the border in my previous cases. I can't duplicate it now but you get the idea.
Bad Tangency
Drive Surfaces only, tip compensation, Auto roll on surface edges
Good Tangency
Drive surfaces, check surfaces to limit edges, center compensation, Auto roll on surface edges
The stock size is identical between the two photos so you can see how far outboard the cutter is traveling. The fact that the cutter isn't traveling out to the edge is what's leaving the little lip on the perimeter.
I can email the file to you if we can't solve it this way (I lost your contact info though). Nothing secretive about it.
I'm just trying to be minimal impact on your time.
