I'm on a roll tonight!

Something else comes to mind in this sequence.

So Ekos requested 10285. Then asked the focuser "where are you?" The focuser responds with 10184 but is still moving. Ekos waits until it stops moving but never asks the focuser "where are you?" again. What if Ekos is using the last known ABS position it received rather than assuming the focuser is in fact at 10285 when it stops? It never asks again, then subtracts 100 from 10184 and issues a move absolute command to 10084 which the focuser does. You see the focuser never reports it's position after the 10184 response. It may in fact be at 10285 when it stops but Ekos may not be making this assumption.

This may explain why sometimes it seems to work. Maybe if the move is small, or if I increase the speed of the stepper motor it will work more reliably?

Just a theory. Ok, enough for tonight!

Thanks

John,

Here are the command descriptions:

So Ekos appears to be asking if the focuser is moving and waits until it's stopped. Although, I'm wonder if once the CMD <:00#> is issued and responded to that the focuser physically stops moving. Maybe? It seems to appear that it does based on the logs.

Let's see what Robert says.

John,

Thanks for the detailed explanation! I understand much better now. Yes, I see what you're talking about now. There does appear to be a problem here. Below is the debug messages from the driver for this example. I think I'll share this with Robert Brown as well who developed this focuser.

BTW, I tried 1-pass Hyperbolic and Parabola again tonight and both failed in the same way! Therefore my statement that Parabola works is in fact false. Also, the backlash setting is greyed out for me. For now I switched back to the Linear mode.

Does this log shed any additional light on the topic? I'm not sure if the focuser commands are standard or specific to this focuser. I'll check with Robert on this.

John,

I've not been able to reproduce this at all. When I manually move the focuser in and out using Ekos it behaves perfectly, accurately moving to where I tell it to. For me I really think it's something in the Ekos Hyperbola algorithm. It runs through the moves but at the end rather than choosing the solution, Ekos chooses the last sample as the focus point. It doesn't seem to happen on parabola. You can see this in the screen shots Massimo and I posted. Backlash compensation is disabled in my driver settings and in the firmware.

Thanks
Ken

I have the same focuser and firmware. Unfortunately, the same problem as well. I don't think it's the focuser firmware because it did it with the older firmware as well. I'm awaiting the new release but for now I use 1-pass polynomial and it seems to work OK for me.

John,

The Unknown Error is now gone. I'm running v319 of Robert's firmware which is the latest.

Sorry, yes I mean Quadratic! I switched to Parabola and it seems to work fine every time. I did try Hyperbolic for a couple of cycles and it also seems to be working well for me. When on Quadratic sometimes it chooses the final sample position as the solution even though the value calculated on the chart is very different. As you see in the screen shot above. I really don't think this would be anything to do with backlash settings.

The next time I power it up I can send a screenshot but I can confirm that both in and out are disabled and all values are zero. The image in the manual is using the Windows test application. These can also be set in the INDI driver which is also set to disabled.

Thanks
Ken

Ken replied to the topic 'Linear 1 Pass gives wrong solution' in the forum. 3 months ago

Ok thanks, I'll try that. For some reason I only seem to have issues with the Hyperbolic curve fitting. In my example above I noticed that 10084 is in fact sample #10 on the chart. So when it says "moving to solution" rather than selecting the good solution it calculated it just stays at the position of the last sample.

Hi John,

I finally got around to updating my focuser to the latest firmware. Backlash compensation is disabled. I tried several steps in and out and the focuser hardware appears to be very repeatable. Unfortunately, I'm still seeing the issue. Here's a screenshot from tonight's testing. The correct solution is 10185 which I confirmed with a bahtinov mask but the algorithm picked 10084 for some reason which is out of focus. I haven't spent much time with the other Curve Fit settings but it does seem like the Hyperbolic fitting causes me the most trouble.

Hi John,

I have it disabled in the settings. Here's a screenshot. I also see there's an error that's interesting! Not sure what that's all about.

I did notice there is new firmware available so I'll load that up tomorrow. I don't see anything in the release notes that would indicate it would address this but who knows. Maybe it'll address that error message I see on startup.

Hi John,

I think one of those moves was a manual move that I did. The last one I think. Once I seen it stop at 6166 I manually moved it to the bottom of the curve. The 6166 position was the #10 sample. I didn't get it in the screen shot but it's there. If it found a solution after 9 samples why would it do the 10th and then stay there?

Thanks for taking a look. To answer your questions:
1. No, there is nothing else controlling the focuser. INDI is running on a RPi with the latest version of all drivers.
2. There is no backlash control on the focuser itself. It just drives the stepper motor to absolute locations.
3. The INDI driver is part of the 3rd Party collection I believe. I see in the log file it's "org.kde.kstars.ekos] - "MyFocuserPro2" Version: "1.0" Interface: 8 is connected.". I believe the source is here github.com/indilib/indi/tree/master/drivers/focuser

Moving the focuser in and out manually goes to the count I specify every time. I didn't seem to have an issue with the 2-pass method in the past.

I've contacted the developer of the MyFocusPro2 to see if I'm running the most up to date firmware just in case.

Thanks
Ken

I also include the filter name in the filename but is PI's WBPP script able to use the filename for the filter rather than the header?

Something else I should mention... this started when I upgraded to KStars 3.6.0 but at the same time I updated the "indi-asi" driver from version 2.0 to 2.2. I've noticed looking through my logs that all my problems are with v2.2 of the ASI driver. I wonder if that's the problem rather than Ekos? I have been unable to find a repos to downgrade to v2.0 to test this.

Thanks

Hi John,

I'm running version 3.6.0 stable on Windows 11. INDI is running on a Raspberry PI but I don't think that's the issue. I just today installed 3.6.1 but haven't tried it yet.

The 6166 is the position of sample #10 which isn't showing in my screen shot. You can see it in the log file. It took the last photo at 6166 and it left the focus there rather than moving to the solution position. Almost like it aborted or something. I attached the full log of the session. It's pretty verbose as I run with debug on for everything. Let me know if you need anything else. I appreciate you looking into this.

Later in the log I switched to "Hyperbola" mode and it seemed to work OK based on the HFR of the few images I captured. Also, at the end of the log you'll see lots and lots of errors.... my USB cable got snagged at the meridian flip I think can disconnected itself. :( Anyway, not related to the focus issue.

I have exactly the same issue. It only started for me with the 3.6.0 update but I also updated some INDI drivers around the same time. I'm also using a ZWO EFW 7 filter wheel.

Have you found a work around for this issue yet? It's a bit of a pain updating the FITS header one image at a time.

Ken replied to the topic 'Linear 1 Pass gives wrong solution' in the forum. 4 months ago

Good day! I can report that I've seen a very similar issue. I was using the Quadratic 1-pass method which normally works well for me. In this case it seems to have resolved the focus point but then selected the last sample (value 6166) as the solution. The best solution was 6261. I attached an image and log entries of the autofocus completion summary. Not quite sure why it did this. It's the first time I've witnessed it first hand but I suspect it's happened during long overnight capture sessions as well.
