Corsair I would love to argue with you about this all night but let me quote from the 2600MC Air manual:
"The camera has multiple DC power ports. You can choose any one
as the power input port, while the remaining DC interfaces can be used as
power output ports, powering devices such as the dew heater strap or
mount."
I also read forum posts where ZWO said a good way to power the AM3 mount (which is what I have) is connecting it to the camera power ports, so that is what I have done.
If the issue is caused by power, I doubt it would be so rare. As I've stated, most nights it works. I think there is a recurring software bug. We'll see what ZWO finds.
