That¡¯s a great idea Michael.

?

Perhaps another way you can test this is do the goto from the hand control unit and then unplug it when it starts slewing?

Thanks

Dear Magnus,

?

Having read all of your misery on this... sorry to read the problem persists.

?

It is quite a mystery, and I can't recall anyone else reporting that type of "interrupted" trouble from a Gemini1 or 2 before.

?

I have only this idea for you to try...

?

Because you can "interrupt" a slew by pressing a hand controller button, I have wondered if there could be an intermittent contact/short in your hand controller buttons.

The question is: do you still get this error with the hand controller removed (once you set up).

After setting up, you can still issue GoTos from a PC through Gemini.net.? Do you still get those Interrupted messages with the hand controller removed???

Maybe you already reported that it cannot be the hand controller... if so I apologize for asking again.

?

Another related question: open your Gemini-1 and unscrew the 6 hexagon shaped top panel supports.? Lift out the board inside and inspect the back of that board.

Do you see any corrosion or discoloration of the traces??

I am thinking that an intermittent in there could mimic a hand controller button press.??

You can clean any discoloration with alcohol on a cotton swab.

?

Very best, and good luck,

Michael

Hi!

Anybody got any ideas on this situation? I feel quite lost. Last night, I was imaging M33. I made a cold start, aligned with 3 stars with mount east of pier, then 1 star with mount west of pier. THen tried to slew to M31 with the computer - OK!. Tried M33 - Interrupted. So I slewed "manually", that is, used the motion control on the computer, until the scope was at M33. Did a plate solve - which syncs (does not update the model). After that, I could slew to M33 - that is, adjusting and centering M33 now worked! Why? If the model was not synced correctly - why did it not just slew to the "wrong" place (could not be much off, given how nicely it found M31) and then update on syncing? Why "Interrupted" at first attempt, but after sync it works?

See also my previous post with images of the time and location settings - anything wrong with them?

Any ideas, suggestions, are very warmly welcome. I'm on the verge of giving up on this and rob a bank to be able to upgrade to a Gemini 2.....

Magnus
