Has anyone found any work around for this issue? Seems like a pretty large problem. This is a big reason I use Ekos, to be automated. Are we still waiting on a fix on the next stable release?

To my best of knowledge nobody knows what is causing this. The workaround (at least for now until somebody figures this out) is to either manually focus occasionally or schedule your jobs such that in between jobs the focuser runs.

Any ways to reliably reproduce this? I cannot see it with any driver.

Wouter and/or Wes,

Just to clarify, my understanding is that this issue only comes up with the "focus every N minutes" checkbox checked.
For those using filters, a good workaround is to use the autofocus-on-filter-change strategy, where as far as I know, no-one has had this issue.
As Wouter mentioned, if that's not possible, and this is affecting you, another workaround is to have a series of short (e.g. 1-hour long) scheduler jobs with refocus at the start of the jobs.

FYI, I have also looked into this, when Wouter mentioned it to me privately, but unfortunately I haven't been unable to reproduce it either.

Yes, I can reproduce it every time with simulator drivers and with my devices. Let me know how I can help find the issue. I’ll do anything to try to help fix this.

What exactly settings are you using? What steps to take? on what platform?

I first noticed it on 1.5.1 StellarMate OS when I updated to KStars 3.4.1 (stable release). but it happens on KStars 3.4.1 on my Mac OS as well. I start up KStars/Ekos, connect simulators/drivers, run auto-focus by manually pressing the AF button in the focus module (Linear/iterative or poly, doesn't matter which), set up 2 o 3 60 second exposures and set the sequence to re-focus every minute in order to save time but this interval doesn't seem to matter.

EDIT: I just tried to run the sequence while skipping the first "manual" auto-focus routine and it crashes KStars every time. Logs attached.

The issue that I am talking about is for when the "Refocus every ... minutes" option is enabled. I usually first execute an auto-focus manually before starting to image. When then during a sequence an auto-focus is triggered because of the "Refocus every ... minutes" option, it will always use the last image of the manual auto-focus run. Logs that show this were attached to this comment:

Wouter,

I have the same camera as in your signature and have been successfully autofocusing on time or filter changes. I'm running KStars/EKOS/INDI on an Intel NUC with 16 GB RAM.

Thanks @RDBeck! That's good to know.

@wcreech19: nightly. I'll revert to stable and see if I get it there as well.

I am using nightly. Here are the first few lines of the log from my last imaging session:
