Chip,
If the grease gets to cold, it will slow down the stepper input into the gearbox. Easy to skip steps. The grease (used loosely) in the older Hurst gearboxes was more like a thin glue.

Dooh! I knew that!
But this just makes my comments even more relevant as the integrated stepper/gearbox is even better sealed than the servomotor gearboxes. Additionally with the higher gear reduction at 150:1 this reduces the changes of the gearbox being an issue even more given the slower speed. These are not stressed and should last almost forever barring severe environmental or physical damage.
There is one thing Bob did not mention (or I missed) was the power source Bob used when the problem was displayed. If Bob was not using a power supply plugged into utility power and Bob used a conventional lead-acid battery that was not at full voltage air temperature may have had an impact on the #492 drive system.
As much as I enjoyed using my Losmandy G11 and GM8 in push-to mode with their #492 drives even if well balanced I did not feel there was much headroom left in the digital drive system. Used visually the #492 never missed a beat but obviously the my leaky brain is less picky than a camera collecting data.
Thoughts?
Chip
