David,

It's a very helpful group - and I am sure they will ask you to check things I had assumed would be okay - it will just take them a while to get up to speed.

The key summary I would suggest you give them is simply:

1. Everything worked great until a battery change
2. Battery change itself seems fine
3. On re-initialise all parameters appear correct (and can be summarised for them)
4. Pointing seems to be horrendous - and it gets worse in certain quadrants of the sky.

That should give more experienced minds than me something to diagnose from. It should also trigger a check if anyone else has seen similar issues and knows the cause and fix.

Do ask if they know of any SS2K users in your geography!

I expect they will wish you to confirm wiring seems okay and confirm no blown circuitry appears evident anywhere in the hand controller or mounts motors.

They will likely wish to know if tracking after a one star alignment is fine or horrendous.

If diagnosis is very hard to do I would ping Chris Erickson in the Group out of Hawaii to have a look a the unit if he thinks that might help.

Will look for you on those groups and see if I can contribute ideas too!

Matthew

PS

Posted there in the Yahoo forums in your thread for the above summary and my view you have set up the controller correctly.

PPS

Would love you to get a PC cable and see if after a one star set up, would any goto commands from an astro control program suffer the same or different consequences from entering the same goto from the hand controller. I am starting to ponder if your co-ords match an astro programs coords then encoders appear fine, so it may be something exotic interfering with gotos.

If you lock on one star then issue a goto a second star which fails badly - then issue the same goto again once or twice een does the mount move at all or think its already on target? If you then press the ID button on the controller does it search and find your target star or report its a long way off? If it finds your target star in th ID function are its coordinates correct.

I do feel we are still making progress!
