Hi William,

Thanks for the additional context. We stopped or never used the USB pass through so I don't think that could be one of our issues. But the mount hanging due to some odd mount stall due to some connectivity issue around the USB cord made me think you are onto something here, at least with our system. In later units they supplied a right angle stress relief dongle to lessen the issue you mentioned.

The grounding this is also interesting as that is something we have been working on at the observatory. We have seen grounding issues creep into a different telescope we were working on. Great ideas - really appreciate you sharing all of your knowledge.

Best,

David
