Ekos (KStars 3.4.0) sending clear_calibration to PHD2 frequently

With Ekos 3.4.0 I'm getting a very odd behaviour. I'm using PHD2 to guide muy mount. With the previous version of KStars, I calibrated the guide once per session, at the beginning as recomented by PHD2 folks. But with the new Ekos version, every time I make a goto to other object and try to guide, Ekos send the clear_calibration to PHD2 and my calibration is ruined

This is an example. As you can see the "clear_calibration" request is called multiple times. This behaviour happens every time I perform a goto.

I haven't found any way to configure when Ekos ask for a guider calibration, any clue?

Anybody knows anything about this communication? Why is Ekos sending those clear_calibration messages to PHD2?

I suspect the reason is due to the mount not responding with a sideOfPier value.

If you are using the Scheduler perhaps you have this setting in "Settings" - "Configure KStars" checked as active:



If memory serves, there was a discussion on the forum here in recent months as to the best way of implementing the "Always Reset Guide Calibration". Some searching should turn up the exact conversation. As I understand it, this will reset the calibration at each new goto position while using the scheduler, however, I am unable to test and confirm this at the moment.

It may be related to this discussion. Side note, the topic title became screwed up in a thread merger.

I was not using the Scheduler at all, but the change introduced on Ekos 3.4.0 tu support this option, affects all the guiding scenarios, not only the ones handler by the scheduler (at least the code that I've read that is now on 3.4.0 version). So, when you want to keep the guider calibration, you must always uncheck this option aside if you are using Scheduler module or not.

Thanks for the heads up

Thanks for the heads up. Reading this thread (well, as it's broken, I follow some links on it) I've found the change introduced on version 3.4.0 that was causing the wrong behaviour. Thanks a lot!

I'm glad you were able to uncover the rest of the disjointed thread. That doesn't happen often.

Some mounts, like my iOptron SmartEQPro+, need this recalibration, because they fail to swap the calibration. The box in the scheduler 'Always reset guide calibration' should be unchecked by default, and only need to be checked when the mount requires it.

My apologies, I was the driver of that change in 3.4.0. Some mounts will simply not function unless they are recalibrated every time they are moving across the meridian.
Simply unchecking that box will solve the problem.

Yes, I understand that some mounts needs this behavior implemented as it is. As I’ve explained in other thread, my post was not about removing this option, but about putting it on a more meaningful place: the Guide module.
