Hoping someone around here has experience in this? We are working on about a 2000 line encoder on a CNC machine that is giving us fits. i confirmed the wiring and power to it is just fine. So I removed it, gave it a little air clean and tested it and was able to fire the machine without errors and was able to jog it a little bit before it errored again. For this reason and my visual inspection, I believe the glass disc just needs cleaned. However, i probably only have about .100" in each side of the disc to get in there with something. Not sure if just alcohol will work? Concerned about streaks.
I won't be able to remove the glass disc without a complete teardown and risk because a bearing is somehow attached and all pressed together. hard to explain.
What I believe likely happened is machine was powered down for a while subject to some colder temps and condensation occurred, which did not damage the encoder, but over time has left a haze on the glass that is very obvious. I think it just spins to a bad spot and cannot see through the fog so throws an alarm.
Willing to order special materials for this repair but rather get some stuff locally and get it back together so it's protected.
