Motors not the problem, I had it guiding perfectly last night, I turned off the buzzer sound using the Ascom Gemini Net interface, which by the way should be updated IMO to include items available through the Web interface that are used to set mount functions such as the 4x encoder update :)

Hi Art,

I haven't really used N.I.N.A. in a few years as I am using the ZWO ASIAIR ecosystem with the Gemini 2 no problems here.? So I don't know what those users had to change to get it to stop doing this.?

But if you do a search here it should be findable.?

Re: DEC: Heavy Duty TR alarm - G11
You could try swapping motors to see if the problem follows the motor.? That would be my next move.

I tried the Wed browser interface and found it not responding when using the HC screen, it would only move scope in one axis

This is not a Gemini 2 issues so much as one of your apps is pushing setting data or pulling setting data from elsewhere in the system.? Several other N.I.N.A. users here have reported various issues after updating their Gemini 2 L6 system which was resolved after fixing their settings.? So it is most likely that you have a configuration issue with one or more of your PC apps.?

The HC will display a warning if the battery is running low when starting up. Yellow warning if it should be replaced soon, and red if it needs to be replaced now:

Re: Gemini-2 L6.12 locked-up
Paul,
?
Today I've been investigating the Bad Checksum and Exception errors, which I posted earlier.
As I got another MeLE Quieter 4C for my another Gemini-2, I setup the exactly the same configuration as before.? This time the Gemini-2 unit and mini-PC were different, but the same Ethernet cable.??Under the same environment, where TheSkyX, SGPro and PHD2 were connected to the unit and running, I got a lot of communications error after the first stage.? However after I power cycled the unit several times, strangely the errors were gone. ? When I looked into the ASCOM.Gemini Telescope .NET log file, there were a lot of Bad Checksum and Exception errors during the period when the communications errors occurred.? This was very intermittent at that time, and there were no errors, very stable for many hours.
So I became confused.? After all I asked ChatGPT about Bad Checksum, in particular, relating to the direct Ethernet connection.? ChatGPT suggested to use a cross-over cable instead of a standard one, which I have used after I introduced mini-PCs.? So I took a cross-over cable, which was used to connect Gemini-2 to ThinkPad X230/X270 in the past.? Until this evening I carried out the test for 5 hours.? According to the log, there were no errors.? I don't know this is exactly the cause or not.? I will test this configuration under the real sky if the weather becomes cooperative.

Re: Gemini2 does not select solar system Objects
As Paul said. ? This is only on older ARM processors that have not been made for a long time. ?The problem is/was an internal microcode hard bug. ? ?As said fixed by mfgr, your G2 will have a newer ARM unaffected by this issue.?

Also best to try use a name in your posts as it¡¯s just forum etiquette.

If you're having issues with automated meridian flips, then it might be worth trying. This has no effect on plate solving or pointing accuracy.

There's no way for me to tell if that's right or wrong for your setup, as it depends on the mix of software and drivers and all of their individual configurations. Since the error sounds within the bounds of what a J2000 to JNow precession calculation might produce, try unchecking it and see if it solves the problem. "Gemini calculates refraction" is also usually OK, but this will not cause a 1 arcminute error, especially if you're pointing 15-20 degrees above the horizon. That setting also depends on whether your software already calculates refraction in the coordinates sent to Gemini. If that's the case, you'll want to turn off that setting, also.

Re: Platesolving not as accurate
Try the precession setting in Gemini.NET. You may need to change it (check or uncheck):
