Question !!! REPOSTED !!! EKOS Polar Alignment Tool no longer work with my Avalon Zero

Have the following:

• Avalon Zero Obs with StarGo (tried all FW:s)
• Pegasus Ultimate PowerBox v2
• RPi 4B with running v2.0.4 of Astroberry
• RPi GPS Hat (Adafruit)
• QHY 5 CCD Guider
• Atik Horizon II
• SSD storage

Like my earlier (and others) post my Avalon behaves erratic with the EKOS Polar Alignment Tool. Goto using plate solving works like a charm every time but the PAT is, as I said, very erratic. Some nights it "will just work" other, like last night, it's a lie to get it to work and I have to resort to PHD2 procedures for polar alignment (not bad but I want to perform everything using EKOS). Again, I'm not sure whether this is an Avalon FW issue, Indilib driver or whatever but it is starting to get annoying. First I thought that there could be some interference going on between the USB-cables (I know it's far fetched but you get crazy after a while) but have ruled that out unless I've had six (6) bogus USB 2/3 cables which is not very likely.

The symptom looks like this:

1. I place my mount with everything attached and started pointing to the NCP (I've synced my home-position and set the parking position beforehand)
2. I enter the EKOS PAT and start the procedure
3. The CCD takes an image
4. The mount starts to move west
5. I wait for the mount to perform a 30 degree RA move but it fails to stop and continues - I've noticed that the RA coordinate for the mount is not updated on the screen while the mount slews
6. I stop the procedure



So, pleeeease, if there's somebody out there who knows of a solution to this, pleeeease don't keep me in the shadows...

MANY thanks in advance!!!!!!!

This seems to be the same issue as for the StarGO2 Pro.

Avalon is not answering to posts. I have requested an update by email a couple of weeks ago, which remains unanswered as well.

Please, check the following:

Slew the telescope with the telescope/mount control in EKOS West and East and check if the RA values decrease or increase, respectively.

Refer to my post on East/West mix-up in the drivers.

Hi!

I really appreciate your input and it is somewhat concerning that you (we?) don't receive a reply on this! From a manufacturing point of view the Avalons are well made but the software seems to be in need of some tweaking. Again, I'm not sure if this is related to FW and/or the Indilib driver. Not here for bashing *anybody* - just an increasingly annoyed Avalon/EKOS user.

I'll try what you suggest when work/weather permits

I agree, the lack of response to this proven driver issue is causing some concerns to me as well.

BTW, you can try this at home inside. You just have to look on the RA values while slewing (no GOTO!) using the arrow keys of the EKOS mount control.

It is such an obvious bug, that I am very surprised that Avalon does not respond with a timeline or action plan for a fix. I am very happy with the mount otherwise, just as you said.
