Hi all,
I'd like to see if there is any wisdom or explanation on the following problem. So, I now have the old Mitutoyo 2axis DRO with glass scales on my new-to-me Lagun FTV2 working fairly well. X-axis is fine, at least as far as I can tell. The Y axis is however behaving really strangely, and the behavior did not change at all after a pretty good cleaning (at least I didn't break anything in the process)
Here is the scenario. Both before and after the cleaning, when I flushed it out with some spray solvent, it began to work perfectly. But as soon as it dries, it goes back to not picking up the travel. This is very repeatable. I don't think the spray (a very safe one I use on lots of electronics and hydraulics) is affecting the electronics, because the odds are more that it would interfere instead of make them pick up motion and then transmit counts just right, I'd think.
Maybe the wet surface is making up for optical perfections or rough glass surface? Any ideas? I'd rather continue to use this old crude DRO while I'm learning rather than just throw dollars at it, though I'm willing to spend some money long term. At least long enough that I become better with machining and am more likely to be able to properly install a new system down the road. Any additional pointers on what else I could do, or why it would have this works-wet, doesn't-when-dry behavior, or whether maybe it's not worth messing with a DRO this old would be really appreciated. Oh yes, Giant Mitutoyo display says RL325L and scale only marked as 400mm and 5micron. THANKS!
