One other thing. Have you hot plugged or unplugged anything into the AVX or plugged any into the wrong socket? Never hot plug or unplug anything into the mount with power on, sometimes all it takes is just a momentary short to fry something and plugging things into the wrong socket will def. fry components. All the Aux sockets are wired the same but guiding port and HC are not, Dec. has its own cable.
I've been very careful not to do that. I did get a response from Celestron about possible causes. Here's what they sent:
Because it is happening with both HC and SkyPortal app It could be the motor but he is only doing it with the one axis so I cant tell if both are doing it.
If it is just the one axis then I would say motor with possibility being the Motor control board. If it is both axis then definitely motor control board.
The unit is new and the customers return window is still available, he is able to use the Amazon replacement route if he would like, however the unit can come in for repairs, and it would be a simple Motor Control swap. Especially since he says he was twisting the power port it could have bent the connector causing it to short?
Either way, our recommendation is for the item to come in for repair.
I also asked about the motor since the mount slewed and stopped after hitting the tripod but kept running. I included this shot of the scenario.
Here's there response:
This action can damage more than he motor, it can damage the worm and main gear.
So I ended up opening the compartment for the power and aux ports and loosened the board so I could see if the power wires had twisted when removing the power cable. They had, and also almost unplugged the power from the board. I untwisted the wires and pushed the connector back on, closed it up and tried it out last night. The scope didn't slew on it's own anymore! BUT, the RA tracking was erratic even after aligning using StarSense. I figured it might have been a bad alignment, so I retried aligning probably 5 more times, each with the same result. I'm leaning on the second response they sent and deduced that the work gear may have been damaged.
Final decision was to return it while I still can. Now comes the process of deciding if I want to re-order the same mount or maybe upgrade to the next level and get a CGEM II EQ Mount and Tripod. Still thinking that one over.
