TOPIC: Driver issues with AP1600 mount

Driver issues with AP1600 mount 2 weeks 16 hours ago #24892

Hello,

I am trying to connect the AP1600 mount to kstars through INDI server running on Raspberry Pi.

In Ekos, in the driver list, I can see:
- "AstroPhysics indi_lx200ap"
- "AstroPhysics Experimental indi_lx200ap_experimental".

If I select the first one, it will fail to connect to the server.
Indeed, on the raspberry, I do not see any "indi_lx200ap". But instead, I see "indi_lx200ap_legacy".
I installed the drivers from the 1.6.0 package distributed here: indilib.org/download/raspberry-pi/downlo...or-raspberry-pi.html

If I use the experimental one, everything seems to be fine.
When I tried to park/unpark the mount, I reached the situation that slews from both kstars and the remote were leading to nonsense moves of the mount.
At that point, even the parking to position 3 (CW down, from the remote, ekos disconnected from the mount) was leading to nonsense moves.
In order to fix that, I had to synchronize the mount on a star with the remote.
I am quite surprised: I thought that this position was not dependant on any mount calibration (azimut and altitude shoud be independant from any time/position)?
Note: before doing my tests, I had not noticed the special instructions about the parking positions.

- How to fix the setup for the legacy driver?
- Or, if you advise to still use the experimental driver, how to avoid these parking/slewing problems?

Thank you.
Regards,
Florian

Use Ubuntu Mate for Raspberry PI, I don't think I will make Raspian packages any more.

Driver issues with AP1600 mount 6 days 17 hours ago #25163

Hello,
Thanks for the reply.
I installed Ubuntu Mate on my Raspberry Pi.
Now, I cannot connect my USB Focus any more :

2018-04-14T20:49:35: [INFO] Error retreiving data from USB Focus V3, please ensure USB Focus V3 controller is powered and the port is correct.
2018-04-14T20:49:35: [ERROR] Error reading focuser ID: Timeout error.

In attached file are the logs.
Version is 1.0 and interface is 8.

Thanks!

Hi fsignoret,

I experimented with an AP mount using both drivers recently with a friend. For the old driver, I think the biggest mistake in using it (at least it was my mistake, I don't know if others have this problem too) was that you have to click the "Cold" or "Warm" button in the INDI Control Panel to "initialize" the mount/driver. You choose cold or warm based upon whether the scope has already been set up and aligned or not. For the new driver, we found we liked that one a lot more because it implements a lot more of the Astrophysics features, connected to the mount and was up and running right away, and we had the most luck with using it. The one big thing to note is that we found there was/is a bug in the date/time syncing. We found the best option was to go into the KStars options and to disable the time and location syncing options. As long as your mount has the correct date/time already set, then this shouldn't be too big of a problem. After we disabled those options, the mount seemed to work very well, connected up right away, and we imaged the rest of the evening without issues.

Also, I will agree with Jasem's post above about using Ubuntu-MATE. You might need to install or set up a number of things on the system though. If it helps you out, you can take a look at my setup script to see what I did, or run the script on your system if you like:

Thanks,

Rob

Hello,

An update on this one: fixed by disabling MessageManager, so now I am operational with Ubuntu-Mate.
I will let you know when I get a chance to test with the AP1600.

Thanks for letting me know about the date/time bug, it now explains why my mount had a wrong time at some point!
Is there a tracker for this bug?

Thanks

Florian

I'm not clear yet about this "bug". It seems everything is sent correctly. Can you perform the following test?

Change the handset location & time to some random values. Then connect to it from KStars using AP Experimental Driver. Make sure KStars Settings --> INDI --> KStars Update Drivers is selected. Enable mount & INDI logging. Now connect to the mount. After connection is established, report the handset current time & location values and also attach the Ekos log.

This way we can narrow down any problems.
