Re: Parking Issue

Steve Reilly



I do have the special close script but that’s only used in weather events and I’ve seldom had that problem but it could have the two times I’ve seen this as both time it did rain hours later. This incident was during a normal shutdown at the end of imaging session timed by sunrise in ACP. I can, or have before, hit the park command in the ASCOM driver and it would /did park and finish closing the roof. In this instance not knowing if the active scenario was of any troubleshooting value I simply closed the roof using my roof controller.

I’ve had this problem from time to time at my observatory. When it happens for me, the scope is left not tracking, pointing up, and ACP Expert reports waiting for the mount to park. If I send  the mount to Park manually in that situation, the error clears and the roof closes. I have not noticed the “Park” button in APCC greyed out in my scenario, and APCC is  where I click to park the mount. It seems to be a problem for me more frequently when the CloseSpecialRoof script executes, so I make sure to avoid opening or imaging when there’s any chance of rain at all. My configuration includes AP1600, APCC Pro, AP V2, ACP Expert, MaxIm DL, SkyRoof, AAG Cloud Sensor, and an optical @Park monitor.

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.
