To add to Gautam's entry: we swapped the cables at the coil driver side (these are the ones that go from coil driver to sat box). In this state, damping is not useable since the MC1 servos would drive MC3.

~70 counts in the sensor means ~70 microns of motion. Since the watchdogs are off and the coil drivers are swapped, this can't be laser beam getting in to the sensors.

WE have to consider that these are some real strain release type events happening in the suspension wire or wire standoff, so may require a vent to inspect and possible repair MC1.
