Good evening Gents.
So there is this poor neglected Bridgy at work that has a Sony LF-200 DRO, the scales are model SR-2711.
One of the guys I work with came and asked me if I'd try to figure out why the DRO is messed up. He said it was throwing out random numbers at any point in the movement of the saddle.
I went and took the lash out of the screw, zeroed the DRO and the dial, and moved the dial by grad marks, noting what the readout said. .001" to .004" on the dial I had no change on the display. When I rolled the dial over to .005", it jumped from 0 to .185". Strange.
Tried it going the other direction. Used same procedure. Moved dial one grad, got a reading of .853". WTF.
I honestly don't know shit about DROs. I never had them on the mills at the old shop.
I looked at the wiring looms from both scales and saw they were crushed. Pretty recently too. The grime that was all over the rest of the cables was not present where they had been mashed by the power feed. I approached the fella that asked me to look at this problem and inquired about maybe the table being traversed in X+ and screwing it up. Blank stare and no comment from him.
I also looked at the reader? that slides along the scale and looked for something loose. Looked up into the slot in the bottom of the scale and saw foam or some such that did not appear to be adhering to anything anymore.
Has anyone here experienced this kind of thing before? If so, any ideas about how I might get it working again?
Thanks guys
Luke
