I am trying to figure out how to as "inexpensively" as possible measure the bottom position of a block for flatness while it is in a fixture.

OK so I've battled repeat positioning and setup on my cnc for a while and I've a pretty good system down but I'm ready to take it to the next level, of which I have no idea. I'm currectly using a partial 80/20 and solid aluminum cnc that is prettty solid but I'm going to build a new one out of steel. I guess the issues I have to deal with are welding or epoxy and pins, what kind of ...
