I cannot switch or edit filters on the SBIG CFW8A Wheel from Ekos.
From the INDI Control Panel, you can switch and edit filters, and the settings will be reflected in the "Camera & Filter Wheel" of Ekos.

It seems that only the filter settings are not loaded from "~/.Indi/SBIG CCD_config.xml" when Ekos is started.

I have purged KStars and even deleted the configuration files on home and reinstalled, but no improvement.

Ubuntu Mate 20.04.5 LTS x86_64
KStars 3.6.1 Stable
ST-7E, CFW8A

What's KStars version and build date?

Thanks for the help.

I tried following the instructions to get the Log, but it doesn't seem to work.
$ gdb --ex run --args kstars
Now when I start KStars and try to enable Debug as described, it immediately disables it.
I was able to enable it only after I reflected the filter settings in INDI to Ekos, so I am attaching the log I was able to get anyway.

According to the log, the version of KStars is "3.6.1 Stable" and the build date is "2022-10-05T04:40:28Z".

What's your optical train configuration? Can you select SBIG in Filter wheel colmumn?

I am currently using a system from Ekos with just ST-7 and CFW8 for indoor experiments.
The specific situation is shown in the attached diagram.

KStars update was pushed today, please update and check if it is still the same issue.

I just updated to KStars 3.6.1 Stable (Build: 2022-10-14T04:48:59Z).
Unfortunately, the situation has not changed.

I had this problem with a QHY filter wheel and the manual filter. I found I had to go into optical train and remove the filter wheel and close, then go back to optical train and set the filter wheel and close and it was OK.

Thanks for your comments.
Based on your experience, it may be that Ekos is waiting for the filter wheel to be flagged to return to its origin.
I immediately opened the lid of the CFW8, shifted the wheel slightly by hand, put the lid back on and connected it to Ekos. When I powered on the wheel, the wheel did indeed spin and return to its origin, but the response on Ekos's part was the same as before.

I need to worry about this some more.

I just installed Ubuntu MATE 20.04.5 on another laptop and built KStars, INDI and SBIG Parport Special driver.

It is a completely clean system but I am having the exact same problem with the filter operation after connecting to ST-7 and CFW8.

Problem solved!
I applied the newly arrived KStars update and the Ubuntu kernel update, and this combination has made the filter operation from Ekos normal.

Build: 2022-10-15T12:30:07Z

Ubuntu Kernel
5.15.0-52-generic

The clean system laptop also now works correctly with the kernel update.

I had similar issue with my ZWO EFW and my ASI533MM. I found that restarting the camera driver would then have the filter wheel show up in the camera settings for selection. To restart it just press the power button icon beside the camera description.

After doing this a few times, I haven't had any more problems, but I did also apply the update from the StellarMate app to my RPi.
