guiding stops: scheduler does not recover

Hi everyone
Getting nowhere with this I'm afraid.
A cloud comes by and guiding stops, but capture continues. The scheduler .or whatever module is responsible- makes no attempt to restart the guiding.
Can anyone help?
Thanks,
Steve

Hi Steve,
looks like the aborted guiding just occurred between two captures. I did not try to reproduce it yet, but it seems like there is a weakness in the scheduler how it handles aborted guiding.

Here a short explanation: Currently, the scheduler only reacts upon guiding problems when it is in the guiding stage, i.e. when it starts guiding. In all other stages, guiding problems are handled by the capture module. Unfortunately, the capture module only reacts on guiding problems when a capture is active. In your case, the guiding aborted exactly between two frame captures and hence the capture module ignored it.

We need to take a closer look how it could be fixed. Meanwhile I do not see a workaround for this.

Thanks for reporting it.

Hi Wolfgang and thanks for taking the time to explain.
If you need help testing any future coding of course, don't hesitate to send it my way. Really need this in the scheduler;)
Thanks again,

Hi Steve,
it would be great if you try to reproduce this bug with simulators. If we have this as a test bed, we could try to fix it (although its not that easy with our two spaghetti monsters, the scheduler and the capture module :-P)

OK. Do you mean setup a profile with pHD2 but using mount and ccd simulators instead of my actual eq6 and DSLR? And leave it running?
Would I need any hardware connecting?

Exactly, no hardware, only INDI simulators for mount, CCD and guiding. You might need the star catalogue GSC installed.

Hi Wolfgang
OK, here we are with the simulators. PHD2 stops guiding but capture continues.
Hope this helps with this issue.
Cheers,

Could you please briefly describe how you forced the dithering error?

Hi. Hit the stop or loop button in phd2.

Hi again
It is EKOS which tells PHD2 to stop guiding, as confirmed by the PHD2 devs:
groups.google.com/forum/m/#!topic/open-phd-guiding/XvDky04qo50
Could we lose the stop guiding requests perhaps, or if EKOS must stop the guiding, could it try again to start it at regular intervals?
Thanks,
Steve

OK, I could reproduce it with simulators. Indeed, when guiding aborts after a capture sequence has completed, the scheduler does not check, whether guiding is running before it starts the next capture sequence.

I'll try to fix it.

Hi Wolfgang
It's not only after a capture sequence ends, it is after any capture of any sequence. If the guiding has stopped for any capture in the sequence, it is not restarted for the next capture.

Great news that you will try to fix it.
Thanks so much for your time.
