I found one bad encoder this year by just spinning the shaft with a drill and monitoring the output on an oscilloscope. With a fixed velocity you'd expect to see a pretty uniform waveform. On this bad one I saw gaps.

I think we've seen that problem too, hence why I am going to try and swap some out tomorrow. I think also, maybe try those MA3 analog rotary sensors. Those seem like they might be better. I noticed that firmware 1.4 is required to run an analog MA3 sensor, are the results pretty good with the upgrade?
