Hello All!



I am using an ST7XME/CFW8/AO7 with Maxim 4.11.



Up till about a week ago, I had no problems. However, a few days ago, I

had massive problems.



A light gradient across the images. there is no light leak in the camera

or scope.



The CFW getting stuck between two filters. There were no obstructions

to cause this.



The CFW rotating when it shouldn't have.



Some of the light images were dark, even when shining a flashlight into

the camera.



I contacted SBIG, and they recommended I just try the camera first,

then connect the CFW and then AO7 cables, to determine the problem. I

did that, and then everything started working.



GREAT! I then went to take an image, a sequence LRGB. It seemed to

work, however, with the last filter, the AO7 mirror wasn't working. I

found this out when I tried to recalibrate the AO7 mirror, and it

didn't calibrate. I then tried to exercise the AO7, and got an error

message that there was no communication with the camera.



I then disconnected the camera from Maxim and cut its power. I then

powered it up, and started again, and it worked fine.



What would cause this? Would a newer version of Maxim help solve this?

Sounds like you may be having intermittent contact connections Steve. You may try cleaning all the plug and cable connections.

Unlikely. It all sounds like hardware problems, not software. The most likely

culprit would be a bad cable.

Thanks Doug!



It seems like most people are saying that. I just have to isolate the bad

cable. I do have a spare AO7 cable, however, Bill at SBIG checked out my

stuff, and said all is OK.



I think it happened after he checked it out.

Steve,



I've had problems, similar to the ones you are describing, with filter selection using an AO7 and CFW8 wheel. I found that replacing the ribbon cable that runs from the AO7 cured the problem. SBIG can send you a replacement cable. Talk to Bill Lynch at SBIG. He is very knowledgeable and helpful.
