That seems strange, when I had this issue I couldn't get the simulator to take more than just one image and then nothing more happen.. did you try the simulator ?? One more thing, I have a SX LodestarX2 as a guidecam and a SXVR-H9 as my main cam.. maybe it's related to the driver somehow ?

All things are possible, of course. I don't believe it is the camera driver, all other aspects of the cameras work how they always have. Both cameras do everything they need to in all the other modules, and even in this one, it will operate normally if I just click the loop button. It is only the guide calibration where it hangs.

FWIW:
Does the mount actually move when the RA Forward action is sent
May try calibrating on the ecliptic to avoid issues closer to the celestial pole
Increase the minimum pulses maybe
Is the FITs folder location receiving the first image ok

The calibration had been working for the last 9 months. This was a recent development when it stopped. PHD is still able to calibrate and track without any issues at the same place in the sky. I don't think it gets far enough to move the mount, though I have not been at the mount when this is happening. I would say this change occurred on Dec 10 or right around there.

I just tried the simulator. It does the same thing there. And now that I think about it more, wasn't calibrate its own button on this screen before?

I just tried the Guiding using a Simulator setup, clicked on the Guide button, Ekos went through all the RA and DEC calibration, completed and guides continuously as expected.

The only thing different I did was manually select a star not Auto.

Good to know, thank you. I wonder if this started when I went with the OAG and my guide scope is selected as the same as the imaging scope. I will play with that a little more as well.

Tried with auto star on and off. Here are my settings screens for the simulator. It is still hanging.

and the scope settings


One other thing just occurred to me. I am having this issue on both machines I have tried it on, but they are both Fedora. I wonder if something could be wrong with the build?

How can devices you have in the "Via"? I has a problem similar to this that I fixed in GIT (but not yet published in PPA).

EDIT: Ok I triggered KStars PPA build, see if that resolves this issue for you.

Upgraded via PPA moments ago; Guiding Calibration and Auto Guide works fine. I also notice the Drift Graphics, Drift Plot and RMS fields are now dynamic which wasn't the case earlier.

Are you saying kcobby that you had the Drift Plot on your screen before your last update, but you couldn't zoom in and out on it? That is strange I both added it and made it zoomable in the same patch!

No rlancaste. I'm saying the Drift Graphic was a flat line, the Drift Plot showed no motion at all (didn't try to zoom previously) and the RMS fields were xxx out. All works super fine now.
