I seem to be having a similar problem (perhaps associated with indilib upgrading to 1.9 - it was working with 1.8?). I can focus by looping and manually changing the position but autofocus hangs after it states it is making the initial move.  The indi control panel readout of the Esatto position seems odd as well.  If you tell it to move to a new position it does but the position doesn't update in the panel.  If you tell it to move again it does update to the new location.  It appears the focuser position isn't updating properly.

Yes, I confirm I had the same issue with the SestoSenso2 driver, I'm not going to update my system to 1.9.0 until someone works out what went wrong, I think it might be as a result of changes to Ekos, as I have not found a specific commit with the driver that could cause this.

I am having the same problem with my Esatto. On autofocus, it does a first move and sits there with a wrong position in the panel. It should have moved 5000 steps but reports a position much less than 5000 steps away from original.

Not knowing how the driver works, it seems as if the driver reads the focuser position only once and waits for the focuser to get to the prescribed position, which it never does softwarewise but does hardwarewise. This, I would assume, would make the autofocus procedure wait forever as it thinks the focuser is not there yet.

This appears to be a driver issue. I need remote access to the focuser to diagnose the problem. If someone can give me remote access via Teamviewer to check it out, please send an email to This email address is being protected from spambots. You need JavaScript enabled to view it.

sent my teamviewer info to support

Thanks, I opened a bug report here: github.com/indilib/indi/issues/1443

I asked Piotr to check it out as he is the driver developer and knows best what's going on.

Not sure if the problem on the original post is already fixed and this is a different problem.
I want to confirm the behavior described in other post above with the Sesto Senso 2 focuser and the last stable Stellarmate:

In EKOS, if you manually tell the Sesto Senso focuser to move to a new position, it moves but the new position is not updated in the left panel.
If you press again, then the left panel is updated.

This is in the last Stellarmate stable and upgraded (After an upgrade on april 29, just now, a lot of indi libraries were upgraded again).
 

A bit more info that may or may not be helpful in finding and fixing the problem for the Esatto/Sesto Senso 2 focuser driver. Similar to what Jabian mentionned.

Just to make sure the problem was not residing in Ekos or between Ekos and Indi, I decided to test my Esatto focuser movements from the Indi panel only. I started from the 180000 'focused' position, set the absolute position input panel to 175000 and clicked on the set absolute position button. According to the absolute position panel, the focuser moved to an 'arbitrary' position between 180000 and 175000. Without changing anything, I re-clicked on the set absolute position button and the absolute position panel changed to 175000 without any movement or motor sound from the focuser. Did the same going back to absolute position 180000 and the behavior was the same: wrong position, click again, correct position displayed.

I wanted to do the same with relative position to see if the behavior would be the same but a zero relative position is, logically, not permitted. I would assume though that if the source of the problem and the solution are found for absolute position, the solution would be the same, or similar for the relative position.

Hope this helps.
 

Is there a simple way to go back to 1.8.9 for sensosesto/esatto since that version appears to work?

I did some tests and I want to clarify some points from my previous post

Using simulators everything works as expected.
With Sesto Senso 2, when you manually set a position, the value is updated in the left panel to a value close (but not exactly) to the previous position (see table)

 

Setting it twice (two last rows in the table) sets the correct value in the left panel.
The focuser seems to move to the position set but I could not test it with the stars. Neither tested yet if the autofocus procedure is affected.

Please let me know if you need more feedback to fix it or if maybe I should report this on a new thread or directly on the Stellarmate site
 

We're following up with the issue here: github.com/indilib/indi/issues/1443

With the fix that is now implemented auto focus is working correctly.
