I have now had a bit of a look at the data base and forum and this issue seems to crop up from time to time in various forms. Mostly related to either over tightening of the balance knob, incorrect balance or the cold being an issue. None of which in my case are relevant. I changed the scopes over last night at 1am and even the TSA is doing the same thing. Although I got it behave for several hours afterwards.
I have checked the wiring, I have regreased the entire RA (RA is the light flashing on the communications board and on the board inside the mount), and made sure nothing was too tight or out of balance.
I have posted on the forum and waiting on a reply from the Bisque boys or someone in the know there. The problem is largely intermittent as the mount can run with both scopes for long periods of time an not have the alarm sound and halt the mount.
It could be the boards, motor (not likely as it is stone cold after hours of slewing), but I am confident it is not the weight or balance. Reason being is that it did it without the worm being engaged and without any weight on the mount at all at least once last night. I will check the electric today and have checked for insect and rodent invasions and that came up with nothing.
If anyone has any ideas it would be appreciated. Having clear skies and not being able to image is a little frustrating I must say. No doubt it is a minor thing and just needs to be found.
