I really don't know enough about DRO's to tell what you're showing...
I had looked into DRO's some years ago and the ones I looked at fastened to the table and had a 'tire' that ran along the way...Didn't look too dependable or trustworthy to me...
I'm looking at several in Travers catalog and I can't tell how they measure the distance traveled except that I don't see that stupid 'tire' so I'm guessing they use some kind of linear gradient to measure with...
Even the 2-axis DRO's are expensive...
