ASI1600 MM C hangs during SGP session

rbumm

Hi,

Since 1-2 month I run into severe problems with my ASI1600 MMC.

I use Sequence Generator Pro and connect the camera via ASCOM.

Symptoms are as follows:

Sometimes the camera will not connect after startup ("no ASI camera found"). After 1-2 computer restarts, the camera usually is found

After starting a session, the camera will often"hang" in " ... Download" of the image, finally drop out and the session is closed with an error. This usually happens after about one hour of image sampling.

What I have tried:

Change the USB cable

Set down USB speed

Try the native driver

Updated to the latest driver

Use Sharpcap PRO

Windows 10

No reliable effects.

Any ideas ?

Thanks and best regards

Rudolf

Update:

In the SGP Log files I find

Caught exception while getting filter wheel position. FW is expecting to be STOPPED! Returning (5) : set - '' is an invalid value. The valid range is: . (ASCOM.InvalidValueException: unspecified

bei ASCOM.EFW2.FilterWheel.get_Position())

and finally

Adding sequence level notification: Camera timeout! No image was downloaded.

Sending Notification: Warning - Camera timeout! No image was downloaded.

Hi Rudolf,

When you have the problem, is the cooling works?

If it works, please test it without cooling.

And please check the device manager when you meet the "no camera found" warning at startup phase.

Thanks

Chad, was this ever resolved? There's a discussion ongoing in the SGP forum about this. http://forum.mainsequencesoftware.com/t/asi-1600mm-cool-wont-capture-images/10868

SGP is aborting the sequence because the camera is not sending an image back.

Sorry, I did not get any further information after that.

For the link you offered, it is also hard to say what happened.

So if you meet the problem, you can email us, we can work together to find out what happened.

Thanks

Chad
