My USB cable should be there in a few days time, I will be able to test this park & meridian flip soon.

This is the cable I am using: smile.amazon.com/gp/product/B07HL7MKNC/r..._title?ie=UTF8&psc=1

Works great.

Its almost the same with me, I usually only use the HC to set and store the home position now and then as well as slew it back to the home position if Ekos fails to do that.

So, I guess, seeing all this different Flip XY degrees past meridian settings in the HC it is not an issue with the HC or the mount. I have mine set to UTC+120min, DST=N and to perform a flip at 3deg past meridian.
I did used Mount updates KStars because to make use of the GPS and I have it now on KStars updates mount - either way it did not work.

Can someone of you maybe share the mount settings in INDI and Ekos? May I can find any difference in comparing those.

Sure thing. Here is the config file used by INDI. You can find yours in the .indi directory (mind the dot in the name!!!) in your home directory. Note that I renamed it to .xml.txt since the forum doesn't allow uploading XML files.

Dank je wel Wouter - I will have a look into that when I´m back home tonight

Correct. See my post here www.indilib.org/forum/ekos/7753-meridian....html?start=24#60677

I finally copared your XML file with mine and I dont see any difference apart from one turned entry in the right beginning. Though I could not figure out what that means...

This is mine:

Showing after "DEBUG" the "ENABLE" on OFF and the DISABLE on ON

This is the example

Showing after "DEBUG" the "ENABLE" on ON and the DISABLE on OFF

No further differences in the whole file - they are (appart from the location coordinates) indentical.

It means that in my case debug logging is on and in your case off. I compared my xml file with the one of El Corazon and found one difference. For him the slew speed is set to 9 and for me to 5. I don’t think that’s thenissue though (even if I said so in an email to him) because for me the RA axis does park. And the mreridian flip goes at full speed as well. I am as puzzled as you are...

Agree, this is not an Ekos problem. The difference must be either mechanical (too much resistance and missed steps when parking - makes sense for the DEC motor, which is underpowered) or rooted in the hand controller.

But how can everything work normal if its a mechanical problem? Normal slewing works fine. Plate solving and accurate slew to target works fine. Guiding works fine. Automatic slewing for polar alignment works fine. Even the slewing back to the park position works fine now. So everything where Ekos needs to move the mount for various reasons works super, apart from the flip (and parking but that I don´t care about). Ther are no strange noises from the gears. And I just tested it with different tension on the gear screws - meridian flip does not want, independend of how much tension is on the screws.

In the HC there it seems that only two things could screw it up: the time and location tab or the meridian handle tab. Both we checked several times now and the time and position is syncronized between KStars and the mount. obviously it doesn´t matter who is updating whom as long as both are sychrone and DST is off. Even if I try with settings suggested from users that have no issues it´s not working.

Can it be that the KStars version on my StellarMate causes this issue? I have v.3.5.0 BETA running on it (BULD 2020-08-29T02:41:24Z).
I did not actively choose for it and it was installed automatically (even if I did set the software updates to STABLE in the StellarMate settings). Also the circumstance that I can´t get a Log-file (wich I succesfully did before) is letting me think that something with my version is not right.

I will install KStars on Windows now just to test if it´s a problem with my Raspi´s KStars... Will report as soon as I know.

Cheers, Nico

Hoi Nico,

Interesting. I occasionally notice, epecially after an imaging session, that the scope doesn't go back to the zero position but that both axes are slighlty off. I notice because we marked the zero positions.


Groetjes, Wouter
