My mill came with a Mitutoyo dro on it. Worked fine for a few years. It now gets decimal points on all of the digits on the X readout. Comes and goes. I can't find any info on it. I would like to get a schematic or some where to send it in for repair. Another idea is to get another readout. I don't know anything about the scales, what kind or if anything will adapt to them. Appreciate any help.
