Re: RA lag both motors stopped

Hi Erwan
Were there motor stall messages when this happened? have you tried adjusting the worm mesh??
things that most often cause/ lag/stall 1. insufficient power 2. worm mesh too tight 3. telescope not properly balanced

Since a week I have a big problem on the g11 gemini2 of mu observatory.
This is the third time I found the mount complexity stopped.
Seems both motors stopped working during the night.
After that almost impossible to move any axes, even after power cycle.
I have the message RA/dec lag message.
I passed the whole Sunday in the observatory trying to find find the failing component
Swapping cable with old ones : work better. (Move a little between fails)
Swapping motor no change
Removing motor no change
Unplug ra motor : dec works normally
Unplug dec motor no change
At the end I was able to retrieve a fully functional mount after swapping the optical encoder of the ra motor with the one of an old legacy svm motor
¡ but only for 2 days.
This night complete failure again.
Even worst. No move at all. Try ten of power cycle. Even reformat of scared
I had to phone someone to move the telescope to be able to close the observatory.
I believe the problem is on the gemini computer itself.
Given the symptom do you believe a repair is possible ?
Does it seems like a known failure `?
Thanks
Erwan
