QHY 9 m and filter wheel
« on: April 24, 2014, 07:43:04 pm »
Hi I just purchased a qhy9l with filter wheel on the used market the camera and drivers are fine. The issue is with the filter wheel. As soon as the power is turned on the filter starts turning and does not stop. I have tried running the filter wheel connected to the camera (and laptop) with the same result, I even ran the filter wheel by itself and it kept rotating. As soon as power is supplied to the filter wheel it turns automatically and does not stop.
I tried re=booting and every permutation of start up with the same result. I have all the latest drivers and the filter wheel does not respond to any commands (using ezcap). I opened up the filter wheel and the magnet is in place.

I think I have localized the problem. It is either that the magnet has lost its magnetism of the Hall sensor is going bad. I am currently trying to re-magnetize the magnet and see if that works.

Reviving this old topic.
I'm having exactly the same issue with qhy9m and cfw1.
May I know how you resolve this issue if you did?
