All of the professional machinists will tell you that the Z reader should be on the knee / column. I can understand the reasoning for that but I'm not a professional in a job shop. Just a homebody having FUN with my machines - and not having to produce "on the clock".

Seeing as how I tend to do a LOT of drilling on the mill, I don't want to spend that much time cranking the knee up and down all the time. I can drill to precise depths over and over again a whole lot faster using the quill. That is why I put my Z scale there instead of the knee. And I have never felt the need to piggyback an additional scale for the knee Z(2). It still has the dial on it if I need it.
YMMV.
