I'm starting to think that little baby accordions on the scale itself -- left and right of the head -- might be the ticket. Just a thought at this point. Let's keep bantering on this...

I do have one minor issue with the x-axis scale mounting and shield in that it limits the Y axis travel in the rearward direction because the rubber chip guard bunches up between the plexiglass and the back of the mill in the last inch of travel, squeezing the plexiglass shield and the dro sensing head.

It looks so crappy, it kinda looks like part of the accordion. :) But, it works. I could not and would not have done the DRO without your inspiration. I did it about twice -- hitting many of the space issues that I think you may have hit too. It ended up being one of the most fun projects I've done in years.
