I just finished installing the Z axe after installing the X and Y axes a while back on my mill / drill, I was so satisfied with X and Y that I ordered a 6 in. model for the Z. It repeats to .001 which is as good as the units costing several hundred dollars. I think to attain best accuracy you must set up both ends of the scale equal distance to the connecting point on the data reader.
I purchased the 24", 12" and 6" units and transformed my 25 year old 1 1/2 hp mill/drill into a very accurate machine. I had contemplated doing this 12 months ago at a cost of over $450.00 from an off shore supplier.
