How do you power the cam? I'm using a powered USB hub. Connecting the cam directly to the RPi (3B) often results in timeouts.
I also replaced the USB cable. The one that's shipped with the cam caused a lot of trouble.

I had this problem a few days ago. For some reason the guiding (PHD2) was not paused or resumed too early or whatever. So the guiding kept driving the mount away from the target. It was a hard fight between alignment and guiding.
