I am increasingly thinking this is a problem of the electrical contacts in the jog wheel that causes many of the phantom touch flickering when the ground is otherwise good. Pulling the jog up a millimeter or two hugging the sides to reseat it (or something) and then spinning it around a few times seems to fix it when it occurs. Might need conductive grease in there on the spindle’s electrical contacts.
