Autoslew - "Ascom slewing" stuck


Recommended Posts

Hi!
Tha last two nights, I had priobem with Autoslew crashing (Not responding).
Both times, it has been when the mount is close to make an meridian flip - the first time, it wen't ok, last night, it didn't. I don't know if this has anything at all to do with my mount beeing close to the meridian thoguh.

Sequence sais in the bottom left corner that "Ascom Slewing" - but the mount it not slewing at all.
Autoslew logs is looking ok (a bit to high current but no error), The last 5 minutes in the log before the crash is attatched)

As you can see, the log sais nothing about making a slew at the timestamp 20:31:20, but in sequence it does. One thing i did notice was that the log in sequence usually sais "Pierside" after the slewcommand is sent, but not for the last slew, which failed.

Has anyone an idea what this might be? Autoslew problem? Ascom? Sequence?
I Have not seen this before, and now, two nights in a row.

I do how ever change the RA counterweight to even out the balance ever so slightly three nights ago, but the current looks better now than before???
Can this have something to do anyway?
It is also between -15 and -20 degrees celcius, so a bit cold... but haven't been any problem before.

Hi Daniel

The current in your log files is quite high for both axes... This might indicate bad balance or bearing problems, though it would be a bit strange if that would happen on both axes at the same time. Very low temperatures may have some influence as well. I do not know what grease ASA uses to lubricate the mounts, but it may be worth asking them. Maybe Wolfgang can give you an answer. Cleaning and re-lubing with a grease that can handle extreme temperatures might be an option...
Succes!

BR, Waldemar

The story continues...

I checked the balance again, and in both axis, both in the eastern and western part of the sky, both at 40 degree alt and 75 degree alt.
In all of the places, the balance is just 0,1-0,2 amperes off at most, so the balance is one of the best i have ever pulled off.

I also checked the motor log for autoslew, there is a bit high current, sometimes going up to 4 amps, so there is some issue - BUT, autoslew has during theese days never showed servo error or pointing error, not once! 

This time, it suddenly stopped in the middle of an MLPT, it did the meridian flip as i should, no problem there.

But the same error as the three last nights occured - it sais, in sequence, "ASCOM slewing" - but there is no slew going on.
Both Sequence and Autoslew became non-responding.

I feel more and more confident that this isn't a balance issue, but a software hickup.

Has anyone seen or experienced something like this before?

Have I set some kind of troublesome setting?

The screenshot is from where all stopped for me. I couldn't open sequence to get that in the screenshot as it was non-responding, but the "autoslew" icon was flashing blue, stating a slew is in progress.

Hi - don't know, if this is also somehow connected to this topic.. 

I'm not sure, but I've the impression that since I changed to window10, I've sometimes simply hangup (with program not responding) and the only solutionm I found is physically unplug the USB connection. 

Georg.
