Bug ID: 410094
Summary: Kstars sometimes fails to wait for a slew to happen
before slew is regarded as complete on the mount tool.
Product: kstars
Version: git
Platform: Compiled Sources
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: mutla...@ikarustech.com
Reporter: deathstal...@gmail.com
Target Milestone: ---
SUMMARY
In some cases when using the mount model tool, KStars/Ekos has immediately
decided the slew is over.
Ex:
[2019-07-19T01:17:54.891 CDT INFO ][ org.kde.kstars.ekos.align] - "Slewing
to target coordinates: RA (00h 00m 00s) DEC ( 55° 51' 27\")."
[2019-07-19T01:17:55.064 CDT INFO ][ org.kde.kstars.ekos.align] - "Slew
complete. Solving Alignment Point. . ."
[2019-07-19T01:17:55.065 CDT INFO ][ org.kde.kstars.ekos.align] -
"Settling..."
This comes from Align::processNumber in align.cpp, which seems to only check if
the Equatorial coordinates show as IPS_OK, even if the mount has had no chance
to update the status. (In this case I had it as 200ms, you'll note that the
Slew to Slew Complete is less than that, and I think the default polling is
something like 500ms from the lx200 derived drivers.) So it seems that there
should be a minimum delay before it fires off, and/or a state change to/from
tracking/slewing before it registers.
Do note this is also kstars running on one machine, and gigabit ethernet to a
mini pc (also running the same OS)
It's also possible that the driver isn't doing something right, but based on
what I can tell, the driver starts doing that immediately after a status update
finishes. (Which is a little talky, but I don't belive that's the issue here.)
Timeline which may be more clear:
2019-07-19T01:17:54.555 (Update, Mode: Tracking)
2019-07-19T01:17:54.870 (Command to sync sent to mount)
2019-07-19T01:17:54.891 (Ekos align module, says send to slew)
2019-07-19T01:17:54.951 (Update, Mode: Tracking as Command not yet sent)
2019-07-19T01:17:55.064 (Ekos regards slew as complete)
2019-07-19T01:17:55.096 (Command to Goto sent to mount)
2019-07-19T01:17:55.292 (Update, Mode: Slewing)
2019-07-19T01:17:55.365 (Ekos mount registers status change)
2019-07-19T01:17:55.660 (Update, Mode: Slewing)
STEPS TO REPRODUCE
1. Keep Aligning and it will sometimes happen. It is not a regular thing. My
assumption is that there is the condition of it getting to that case only
sometimes.
OBSERVED RESULT
Using the mount model, sometimes the Align module decides it's done with the
slew, even if the slew is far from complete.
EXPECTED RESULT
Wait for the slew, solve, sync, slew, until everything is done. As it does,
some times.
