Hello,
Even thought this issue was reported by me and some other people over the last few months, I am surprised that other people do not complain.
Maybe something is wrong with my config?
Everything works fine in RPI client but under Windows (currently KStars 3.2.1) the PA procedure doesn't go through (it tries though...).

Symptom - start PA procedure, 3 rotations, select star, next, press "refresh" every 1 sec (tried different refresh intervals, different exposure times - didn't help),
-- it doesn't refresh. Takes a frame and then the log shows "<strong>cannot capture while CCD exposure is in progress. retry in 10 sec</strong>".
Sometimes it refreshes once if I wait long enough. Sometimes it refreshes for several frames and then stops. Sometimes it doesn't refresh at all.
At the same time, framing in the Focus module works, looping in the Guide module also works.
I have two ZWO cameras.
My guide/alignment camera is ASI120. Main camera is ASI294.

But again, it works great on RPI client.

Thanks!

Hi Max,
there must be some imaging taking place somewhere else using the camera that you want to use for PA.
I experience from time to time that a running PHD interferes although it uses the other camera. So please try to run PA with the equipment disconnected in PHD.

Another possibility: is a focusing running in parallel - or something else using your main camera? That’s wat the message says.

Wolfgang,
That the thing.. no imaging is taking place anywhere. I don't use PHD.
I am running the PA procedure using my ASI120 camera.
Procedure goes as it supposed to - takes pictures/plate solves - rotates, presents the solution.
But when it comes to the "refresh" step, Ekos thinks that the camera is busy...
At this point I can go to the Focus module and start/stop the framing loop - this works fine.
I can go to the Guide module and start/stop looping there - works fine too.
So, the camera is certainly is free to use...

Probably I have some sort of a mismatch in my INDI config somewhere.
Of course the weather turned bad and I cannot troubleshoot.

Thanks!

Hi Max,
please be so kind and post the logs. Maybe we can find the explanation.

Interestingly, it fails when I use simulators too... o_O
(currently @ KStars 3.2.2)
Attaching the log.
Fail occurs @ 2019-05-19T16:52:19.108
As with the real setup (not simulators), it refreshes occasionally, sometimes even for several frames, but then stalls forever.
If I hit Capture & Solve, it captures/solves and then refreshes one or several frames.
Thanks!
Just to remind - it only happens on my Windows client. On RPI all is working well.

Hi Max,
one thing that is strange: it seems like the GuideSimulator creates the image. Please check whether the right camera is selected. The guiding is not visible in the tab, but is it possible that the guiding has been started?
