TOPIC: Losmandy Gemini 2 stops responding to slew commands

Losmandy Gemini 2 stops responding to slew commands 1 week 2 days ago #20878

I have been having some issues after commanding the mount to park, I frequently find that it stops responding to slew commands. I can change the park position and disconnect / reconnect and it parks fine. I unpark and then slew but it responds with '[WARNING] Please unpark the mount before issuing any motion/sync commands.'
I try reconnecting with cold/warm and restart options but nothing seems to make any difference.
Park command shows [INFO] mount is parked [INFO] mount is sleeping...
Unpark command shows [INFO] mount is awake...
I set RA and Dec co-ordinates and [set] and the warning above shows but no motion.
Selecting [Unpark] shows [INFO] Telescope already unparked.

There is a pending comprehensive Pull-Request by Eric for Losmandy. It should be merged within a day or two and then you can re-test afterwards.

The changes I have made should fix the issue you are seeing. Like Jasem said it should be merged soon, I just finished correcting a merge conflict so it should be good to go.

How are you connecting to the Gemini?

I am connecting to the Gemini using USB.
I have previously tried Ethernet but had no success at all.
All is running ona Raspberry Pi 3 on Ubuntu Mate.

The updates have made a significant improvement to the Gemini reliability.

I am still having some issues - after hanging I found the following
Dispatch command error(-1): INDI: Could not find property EQUATORIAL_EOD_COORD in Losmandy Gemini
<setNumberVector device="Losmandy Gemini" name="EQUATORIAL_EOD_COORD" state="Ok" timeout="60" timestamp="2017-11-19T10:41:18">
<oneNumber name="RA">5.693333333333333357</oneNumber>
<oneNumber name="DEC">-69.271111111111110858</oneNumber>
</setNumberVector>

Also, a question - does the Gemini software handle a merian flip, I found imaging stopped last night when hitting the meridian. A message similar to flipping was the last command.

I didn't do anything specific in the Gemini driver code to handle a meridian flip. I think the meridian flip is handle deeper in ekos/indi.

I have seen a few messages like the one you mention but it never seemed to cause me any trouble so I didn't track it down further.

Ekos doesn't do meridian flip per se. When the mount cross the meridian and Ekos wants to "flip it", it simply issues a new GOTO command to the _same_ coords the mount is already tracking. Mounts (depending on their settings) would then automatically perform the meridian flip.

That is the way I understand that the Gemini systems works as well. I think there are some settings in the Gemini that control how far past the meridian it will track before it flips.

Most of the targets I have been imaging since I got the mount are close enough to the meridian that my mount will tend to start out pointing west and looking "back" past the meridian to the east so no flip is necessary during the session.

You should have set your Gemini mount's limits using the hand controller. That is how it knows how far is too far and when it should stop tracking, make a loud beeping noise, and let the user know it should be flipped.

The mount software has limits set. That is not a problem when slewing.

The problem is that I had the flag set in Ekos and it appeares to have issued a flip command to the mount but nothing happened and it just sat there waiting for the remainder of the night.

I was wondering where the issue might be.
