I've been having problems with the DRO on my mill of late and had been putting off looking into it.
A little bit of working "back to the dials" is good motivation.
I was experiencing E20 readings on the X scale so I switched the inputs to see if it was scale related or in the electronics of the Mitutoyo DRO. The problem switched to the Y scale so I knew it was in the reader head or glass scale.
I removed the plastic "wipers" and carefully wiped the glass scale with a nice clean cloth.
I then put the wipers back, ooops better get the camera, better late than never.

The plastic shields (I guess that's a better term)
came out and went back very easily.

Then I remounted the scale. I know, I know how come it's such a long scale for the X of a mill. It's because it came from a large VTL.
(Thanks again Claude)

Back in business both X and Y behaving like they should.
