Re: Parking Issue

Have another look at the screen shot and APCC. Does APCC not have Unpark as
being Active choice and Park greyed out (inactive)?

Mike I purposely left it as is for now in case there was a need for remote
login to investigate. In previous occurrences I could indeed park the mount
via the ASCOM Park command but that doesn't help understand the cause of
this situation and offer any solutions so I left it as is after closing the
roof for safety reasons. I had hoped there might be some procedure to try
before resetting things.

Hi Steve,

This is a recurring problem that I've often blamed on ACP but am
rethinking this as the screen shot shows ACP attempting to park, the ASCOM
driver says it's parking, and APCC says it is parked.

Your screenshot shows the mount is unparked, with tracking stopped,
according to APCC.

There's no way to know for sure what happened from a screenshot, but because
the mount is not parked, the driver cannot indicate that the mount has
completed parking.

This is a recurring problem that I've often blamed on ACP but am
rethinking this as the screen shot shows ACP attempting to park, the
ASCOM driver says it's parking, and APCC says it is parked. I'm
guessing that ACP gets the information from the ASCOM driver so yes,
it actually isn't parked. This is a rare problem but when it happens,
once long enough to have let rain fall on the equipment, it causes
real problems. The mount must be parked before my roof can close so
using a direct close on moisture reading can't work. I had hoped to
find a solution but I don't see this now. The screen capture shows the
roof closed only because I closed it using the close command in AstroMC and
the mount was already in the Park 4 position and had been since 0623. The
last image had downloaded at 0531 and the shutdown script was executed at
0623 if I remember correctly. It was a brief notification from Windows 10
but those were cleared after reading. Not sure if any record is made of
ACP doesn't have a shutdown record as it seems that is made after it
completes which it didn't. If there is a log somewhere else to backup
this event I'm unaware. Maybe APCC can pinpoint the time as it seems to
show the mount parked?

Anyway the issue remains, the roof was wide opened, scope was in the
Park 4 position, my inline Microswitches wired in series were both
closed (continuity signal to the relay) proving a safe position for
the roof to close, the roof was manually directed to close in AstroMC
which it did successfully, and yet ACP still shows the mount as "Parking"
as does the ASCOM driver but not APCC. The difference is that ASCOM and APCC
show the mount at the parked position whereas ACP shows what I assume is the
position it was prior to being commanded to park.
So the question is, where is the log jam and who is responsible for the
stall? How can I prevent this?

I hopefully will have Good Night System fully configured today but
that only notifies me via smart phone of these failures if I set it up
correctly and I have cell signal. It doesn't correct anything. The system is
still in this "Parking"
phase and I'll leave it like that hoping that Bob Denny or other
person has some idea to tracing the problem. I can stop this and power
everything off and start from scratch with a startup script run but
that only puts me back at square 1 and doesn't identify the problem. Is it
a communication issue where a request is sent and waits forever and if so
why can't there be a reasonable time restriction before another request is
sent or other action is taken?

Wide open to ideas/suggestions.
