I recently noticed some sort of a loose with the RA gear box - see attached picture - of my CEM40 which might have contributed to the DEC backlash of 2400ms recently reported by PHD2. It used to be well fixed on the mount but it is now moving eastward or westward by about two milimeters. In fact, everytime I change the RA direction from east to west and vice-versa there is a 2mm delay between the command and the response. Obviously the hex bolts holding the case on the mount have become loose, most probably through vibration. I tried to screw them tight but I have no idea how to access them (they seem to be located behind the gear).
I informed iOptron of the issue but I have received no answer yet.
(Customer service seems to be swamped).
Has anyone ever run into this issue before?
