I just experienced this exact same issue last night! Did you ever figure it out?

- CEM120 EC2
- Lodestar X2 w/OAG.

This is new for me.  I have had no trouble running automated flips before, but I really haven't needed to in about 5 months.  So last night I was imaging and had NO trouble calibrating the internal guiding.  In fact, I have NEVER had trouble with guider calibration.  It just always worked. 

But last night I was imaging - and guiding - and all was great.  Until the meridian flip.  After that, EKOS slewed back to the target, solved it, and then started the calibration run in the guider.  This usually goes without any trouble.  But last night it failed when the DEC was reversing.  The RA was fine.   But once it started to reverse in DEC, it failed and said it lost the guide star.  But the FOV looked fine to me.  I tried five more times to manually calibrate and it failed every time.  I increased he guided six, and adjusted the pulse time.  No change.

Then I went back and re-aligned the scope with a new plate solve.  After that - the guider calibration worked again!

Has anyone sen this happen before?

I added a temperature probe to my Esatto focuser, and noted that EKOS monitors the Esatto MOTOR temperature in the CCD autofocus routine, and also in the Statistics panel.  I should have grabbed the EXTERNAL temperature not the motor temperature.  INDI shows both temperatures - but EKOS grabs then wrong one,

I use a C11 EdgeHD at f/7.  Here's my settings for my Esatto focuser.
You will also see that I set the Annulus to prevent focusing on any far outer edge stars nor the center.

You are going to want to find others who have the same focal length lens you are using - or somewhat close. There is a huge difference between focus settings with a 350mm focal length APO and a 2800mm focal length C11. The longer the focal length, the worse seeing has an effect.

But for me (C11) my initial focus jump needs to to be at least 4,000 steps - or the focus routine fails.

I see that EKOS has the option to do unguided dithering, so I tried it last night.

1.  It worked, but seemed to only dither in one direction.  Is that normal?
2.  After dithering - it turned on my autoguider!  Is there a setting to stop that?  I didn't have the guided dither option turned on, as you cant turn on both guided and unguided dithering anyway.  But after it dithered - it went back and turned my autoguiding back on.    That shouldn't happen if I am using UNguided dithering.

Could be, not really sure. But I don't have a tracking issue imaging at 1956mm focal length. Examples seen above.
I have not tried 1-1 yet. But since I see no tracking issues, I'm not sure I need to. I can see errors at 0.4" easily and right now I rarely get those anymore. I am keeping about 90% of my images.

Not sure if it makes a difference, but I am in central NM at 7,000 feet altitude.

I do guide with an OAG at 1956mm focal length - f/7.
