Hi!
OK, then I understand a bit more. How come you do not take the
Kstars log? At least I feel that is more readable, and you can see
what Ekos is doing.
Few more things:
Do you run PHD2 connected to Ekos or fully independent?
I run PHD2 as well with Ekos, I do not have the "Stop guiding
when mount slews" checked, but I have no experience of that
causing any problems.
Is your issue the wild runaway slews (what I understand as what
you mean by "bad slew"), or that slews are aborted by guiding? I'm
not sure I understand which. And what in the log makes you
conclude that the guide pulse leads to aborted slew? I don't
follow you there.
Again, maybe you know more about this than I do, I'm not a
programmer but have been using this setup for a rather
considerable time now.

Hey Magnus,?
This log is from indi. I run the indi server with -vvv argument
(giving a massive log file). I parsed it and found both a good
slew and a failed one. As you mentioned the good slew does not
have any guide pulses in it. The bad slew does though. The log for
the bad slew is attached a few messages before the good one. I
broke down the log in this post in this thread:?/g/Losmandy_users/message/66491
The bad one has this just after issuing the slew:
2020-05-27T06:42:20: Driver indi_lx200gemini: queuing
responsible for <newNumberVector device='Losmandy Gemini'
name='TELESCOPE_TIMED_GUIDE_WE'>
It's not clear to me what the gemini is supposed to do if it
get's a pulse during a slew. What it appears to do is abort the
slew, but the indi driver never seems to realize that the slew
is aborted.?
I looked it up in the indi code lx200telescope.cpp, and
lx200gemini.cpp and don't see any logic for aborting pulses
during slews. There is logic for that in phd2, but it does not
seem to be working. I didn't look up that code...?

Hi!
I'm not sure if I'm helping or just confusing, but thought I'd
chip in since I have a similar setup.
I found your log for a good slew here:
/g/Losmandy_users/message/66498
However, I'm not sure what kind of log this is. Is it from Kstars
(~/.local/share/kstars/log)? Or from Skysafari?
In either case, I cannot see any pulses during slew. And no slew
command as such. Mine looks like:
[2020-05-26T23:46:02.089 CEST DEBG ][????
org.kde.kstars.ekos.mount] - Slewing to RA= "18h 29m 41s" DEC= "
32¡ã 15' 39\""
[2020-05-26T23:46:02.092 CEST DEBG ][???? org.kde.kstars.indi] -
ISD:Telescope sending coords RA: "18h 29m 41s" ( 18.4947 ) DE: "
32¡ã 15' 39\"" ( 32.261 )
If you could point me towards where you see pulse guiding during
slew, I'd be happy to see if I can make something of that.
Best,
Magnus

I did enable "stop guiding when mount slews" in phd. That feature
seems to be broken? on the PhD/Indi stack for some reason. I let
the Indi people know as well. So my workaround is to stop guiding
before each slew, and that seems to solve the problem.?

yeah it seems that way. what a hassle, sorry to hear that but glad there's a temp fix
I'm surprised this hasn't come up sooner

I looked at that thread - again, it seems specific to the Indi driver.
i have not experienced that problem with the ASCOM driver. if i can find the time i may try out the indi driver to see if I can replicate that
[Edited Message Follows]
I've posted and analized the logs in this thread. If you look at them you'll see the guide pulses after the slew starts. I've also started an Indi thread and posted a link here.

Hi Jamie
>>> But it sounds like the Gemini software should be able to handle guide pulses while slewing, and it seems that it doesn't, so that's the second issue.?
Did you try enabling "stop guiding when mount slews"?
PHD for my windows ASCOM setup will continue issuing guiding commands when I forget to enable the option to stop guiding while slewing. I haven't run into any issues with that on the windows platform.?
Brian
OK, so I think that I'm on to something here. M101 went behind a tree so I had just a few possible targets, each was having it's own issues, so I decided to just play around and test the guess about slewing while guiding. I hopped around the sky for close to a dozen targets. Some east some west, all over. No issues at all. I started guiding, then did one slew and I have the issue. SF is now stuck not finishing it's slew. This looks to be the problem. So the Ekos/indi/phd2 stack is supposed to not do guiding while in a slew, but it does anyway. That's one issue. But it sounds like the Gemini software should be able to handle guide pulses while slewing, and it seems that it doesn't, so that's the second issue. From now on I'm just going to be careful to turn off guiding before I do a slew.?

If you can give me the cable lengths you need from the NGC box to the encoders I can make up a cable for you. A photo of your encoder hookups from the RJ1-2 jack (RJ-11s are the same size but have 4 not 6 conductor positions) to the encoder will assure they are standard pin outs. Sometimes RJ-9 4P/4C connectors are used. These are norrower than the RJ-11/12s. RJ-9 4/4s are commonly used on fax cables. Tangent built most of these early DSC displays and sort of set the standard. They were also the folks behind the 492 DD System.

Hi!
I'm not sure I understand your problem, but you mention Ekos and
PHD2 guiding while slewing. That's more of an indi issue. Do you
have a log showing that, or what makes you think it guides while
slewing (I mean, sending pulses)? Maybe better to place in another
thread or even the indi-forum?

You're right, quite the drift.?
So I'm out tonight and just got one of those wild slews. This time it happened during a plate solve, so it really seems like the same issue that the beta firmware fixes. I had forgotten to hit stop on phd2 so I wasn't able to test that. It's supposed to rain in a few days, I'll install the beta firmware then. Thanks for all the help by the way.?
|
i'm not sure how we got from TCP and Indi discussion to this, but absolutely give it a try and love to hear the results
Seems like this may be the same issue as Magnus found in another post. I'm going to try the beta firmware as that seems to fix it.

Oh, is that a setting in the handset?
|
i was referring to something else - "stop guiding when slew detected"
?
PHD can send guiding commands and they do not interfere with slewing. or i should say they don't interfere under normal circumstances.?
?
?
I'm guiding with PHD2, and do have the option set to not send guide commands, but from the log they are being sent.?

What are you using to guide?
Usually guiding is unknown to the mount, and it's really up to the guide software to stop guiding on slew (there's an option for that in PHD) but i would not expect guiding on or off to impact ability to slew
I'm going to get a reduced log of the successful slew and post that here. Next I'll post both to the indi forum. I haven't narrowed down which condition triggers it. I'm wondering now though if I should explicitly stop guiding before slewing and see if that helps. Would you expect timed guide commands that happen during a slew to cause any issue??
