Readout flickers with motor running (glass scales)
#3
It doesn't seem to drift. The flicker starts wn the motor is about halfway spooled up, and gets worse until it reaches full speed. I'm using the latest glass scale adapter, purchased a month or 2 ago.

I suppose it could just be a faulty scale. I tried running a wire from a mounting pad on the adapter, to the machine, thinking maybe it was a ground issue, and noticed the adapter shut off when I touched the wire to the machine. Somehow I was getting 5v between that wire and the machine frame. I troubleshot this to a tiny solder bridge under the tiny ribbon cable in the read head itself. I removed the solder bridge, and that fixed the weird voltage/grounding issue, but the flicker persists.

I'm at work, I'll post pictures and a video when I get home in the morning.
