Re: Multiple Encoder issues

A few years ago I ran into something similar. I banged my head against the way for the better part of a day trying to isolate it.

We swapped encoders, we continuity tested the cables, even checked for bleed over on each pin. We could find nothing wrong.

Purely by accident, one encoder was not plugged into the digital side car and suddenly all but that one were working flawlessly. I replaced that cable with a new one and presto everything started working.

What it turned out to be was ONE bad encoder cable, where in cable, heck if I know, because it passed every test I could do at the event. But that was it.

So my suggestion would be to disconnect all your encoders, and then add them back one at a time until you find the culprit.
