Sonny, you were never a member of Gemini-II users group, at least not under the same login you're using here (this is the Gemini user group, primarily focused on Gemini-1). You may want to join that group if you're using Gemini-2, you'll find more about that controller there.

One thing you may want to try is to set the ASCOM driver setting to use goto to flip the mount:

Thank You Edward!
I've discovered I'm not a member of any group except for the Gemini II group, which I find odd.
So maybe that explains why this lost lamb is bleating in the wrong pasture. Maybe I got dropped for lack of posting? I don't know.
I'm just thrilled to have gotten your reply to my post.

As recommended, I have set my Limits to my particular equipment.
Western Safety limit: 101.4 (Yours was 101.3 if I remember correctly)
Eastern Safety Limit: 99.26 (I don't recall yours.)
These are set to avoid crashes, per recommendations in my Gemini II hand controller, and saved as my default.

I did use most of Cuiv the lazy Geeks you tube tutorials to set up my NINA in my mount computer.
Even though many of the tutorials refer to older versions of NINA releases. My currant version is 2.3.2.9001, I picked and did my best to apply the knowledge imparted there.

At one point I ferreted out where another user posted his limit settings. I tried them out of desperation and Glory Be, they worked for my GM811G HD. I was ecstatic.
I was waking to a parked mount with a date file full of all my images from my 8 filters....
Then, Windows shoved an Update into my computer and basically shot holes through my drivers that weren't Windows issued/approved.
I had to completely redo my laptop for my mount and have restored everything to working order EXCEPT?NINA's Automated Meridian Flip. So frustrating!

So that is what I've been trying to do for months and months now, but I'm missing something.
And I can't find the post that had the settings that worked, for a few folks.
And I have yet to hit on what I'm doing wrong, or have set wrong.

Sonny, did you find the spreadsheet in the Losmandy group that i uploaded to go with the presentation? ?It lists the other parameters you might need to set.

does a MF happen when you goto a target from gemini controller when you are on the “wrong” side of meridian (no NINA)

My gear is in storage so i have not tested with the most recent NINA. I last ran imaging at end of Nov23.

I'm fighting with NINA and Meridian flips again. I'm posting in hopes that someone might be able to help me out.
At one point I copied in a fellow Gemini II members settings and POOF! Everything was working great! I could finally pick an object and my GM811G HD would follow NINA controlling it and run all night collecting images.
Windows did one of its infamous updates and broke my drivers and other Non-Windoze programs (Which is about every Astro App there is.), by the time I got my laptop fixed, I could no longer do meridian flips. Long story short.

So I've been trying and trying to fix this again... for months now. I'm really close, really close.
I've gone through over and over. I have my limits set to MY equipment's settings, which happen to be very close to Edward's. (We both happen to be running 5" refractor telescopes as well.)
I've spent days now doing test Meridian Flip runs with NINA. Picking an object near the Meridian, loading it into a test target set in NINA's sequencer I've dumbed down to run in Daylight, so it isn't trying to plate solve or do other automatic operations involving my cameras. (They're capped)

It goes into a normal Automated Meridian flip, walks through the steps, even ends out like normal. Then continues the sequence.
Trouble is: The Mount never does the flip. It just sits there until it limits out. Which was the old problem, until... I started using the limit setting I found here. Which I cannot find again. About all I can recall was the posters name was David, I think. But he had posted the limit settings he found that worked.
So I've been trying to duplicate the past successes. Without any success.

I've run the ASCOM diagnostics. I've downloaded the latest driver for Gemini (1.1.23)

One other "clue" When the Automatic Merian Flip fails, if I stop NINA's sequencer, Use the Gemini virtual controller to Park the mount at CWD, then restart the sequence in NINA, it comes up from the Eastward side and will continue the sequence until it is completed.

If in UK David is closest but I ask why do you think it’s an EEPROM ?

Yes they can go faulty but it’s kinda rare?

UK - you have repaired my units before - just change the serial port on oine and replaced the power switch no my spare unit...? I shall call you

?Mark,

What is the control panel? Do you mean the Gemini 1 controller board in the metal case or the Hand Controller? If you mean the main circuit board in the Gemini 1 metal case you may be better off contacting Michael Herman and discussing how you diagnosed the EPROM as the issue. Michel is a Gemini 1 component level repair expert and has seen every it all and will know what the problem is.? ??

The G-1 manual says 9800, N, 8, 1 If your comm port settings are wrong, strange things will happen.? Usually when a Micro communicates with an RS232 chip, it will control the data starting and stopping so that buffers in the Micro don't overflow.

madastro,

Michael Herman is the ultimate Gemini 1 hardware debugger.? The older Gemini 1 boards often have issues with their I/O ports as they are not protected and sometimes are damaged while being connected incorrectly or through static discharge. Being fairly old now many have had experiences that have caused them to develop issues at their I/O ports. The issue as I understand it the serial I/O chips are basically connected directly to the ports which leaves them very vulnerable to this sort of sneaky damage. Mike probably replaced the RS232 I/O ICs and may have done other mods to improve the Gemini 1 ports and power supply.?

That said I think NINA has a high rate of data going back and forth between NINA and Gemini and this amount of traffic can overcome the speed of the Gemini 1 I/O processing which then corrupts the data and can cause issues because the position and data don't match up. I think this was part of the issue found while the Gemini 2 Level 6 firmware was being developed and one of the issues that was resolved to eliminate the small mount moves post plate solving to prevent what appeared as a run-a-way mount situation.?

Anyway BEFORE you email Mike Herman verify your USB to RS232 converter and cable are handshaking 100% correctly otherwise nothing will solve the issue. This is a kind of tricky thing to determine unless you are a hardware software person from the olden days like Mike and I are LOL. If not just email him and see what he suggests.?
