When I had a loose cable connection at the HC or Gemini unit mine used to reboot a lot so maybe spray some DeoxIT or other on the cable pins and reseat them a couple of times.
?
My test for cable seating was to start the unit with the HC sitting on something solid and see if it comes up OK - then pick it up and see if it stops working or reboots.
?
The next step for me was to open and check the HC internals but I expect you will get some more experienced advice from others.
?
Good luck

I have a brand new G-11 with the Gemini-II received a couple of weeks ago.?? Due to weather i've only been out three times.? I noticed my first night the HC reluctant to accept my pressing of "buttons" on the screen and at one point the system froze and I had to reboot where upon it worked fine.?? The previous session went fine, no problems.
?
Last night I drove to a nearby dark site and started a quick start.? After selecting G-11 and querying GPS (which it did and received location) pushing the "next" button was to no avail.? I tried a reboot and that's when things went off the rails.? The startup screen with logo would appear and then a very brief message "push screen to re-calibrate" which i tried a few times which initiated seconds counting down to start but then back to the loop of "initializing HC" then "connecting to Gemini".......? and then screen would go dark and back to startup screen.? This death loop continued no matter how many times I disconnected all cables and rebooted.
?
Any easy fix for this?
?
Thanks!

Re: AZ8 with Gemini 2 and go-to with servo motors
Rene,
I would be interested in Beta Testing with you on this project. It sounds like fun.
I even already have a smaller solar panel 7 watt I could utilize for results.
And a lot of electrical background, including being a registered solar powerplant, 5.88 kWh with my utility. (Roof mounted}
?
But I've always been interested in tracking panels. I live in a "Solar Hotspot" on a finger of the Mohave Desert. (Mo-hav-Ie)
?
I would be using my GM811G HD. My thoughts on this would be to do a slip-on mount to my telescope, then let my mount do the guiding.
(My telescope is a bit heavy for me to take on and off my mount.)
If this sounds interesting to you, please contact me.

Re: AZ8 with Gemini 2 and go-to with servo motors
Hi Russ,
Paul is right.
I have a prototype of an AZ8 with servo motors I used to
developing a Solar Tracker. This can track the sun all day with a
telescope or with solar panels. Keeping the panels perpendicular
to the sun all day nearly doubles their efficiency. The nice thing
about it is that the tracker follows the sun from dawn to dusk, at
dusk it moves to the position where the sun will raise next day
and puts Gemini into sleep mode until sunrise, then it restarts
tracking. The Solar Tracker is a standalone application for Gemini
and wasn't sold as a product.
The good thing about an Alt-Az mount is that
meridian flips and Safety Limits aren't that important compared to
a GEM, alignments are easier and so on. It makes it easy to set it
up and use it, it can be fun.?
While working on the Solar Tracker I've
improved and refined Gemini's Alt-Az operation mode. Alas, there
was never much interest in Alt-Az support, so the state is still
somewhere between experimental and Beta, despite it is already
quite usable. If there would be some people interested in Beta
testing and giving feedback I may go on with the development and
include the Solar (Lunar, ...?) tracker...

Hi Russ,
?
Scott Losmandy will likely give you a better answer. I don't
own an AZ8,? but just looking at specs, AZ8 implements a
variable slip clutch on both axis, just like all other Losmandy
mounts. What that means is that you can push-to to the desired
sky position without disengaging or turning off the motors or
Gemini. What will happen is that Gemini will lose track of the
sky position when you do this, because the motor encoders are
not used when you push the mount manually, so Gemini is not
aware of this type of motion. A simple Sync operation is then
needed to let Gemini know where the mount is positioned if you
want to continue using Goto's. Or you can just use push-to for
the rest of the session -- your choice!

manually swing the scope to a different portion of the sky
while the power is still on? ?I'm asking about this because
I know with the Rowan AZ100 mount its motors must be turned
off in the Rowan app before manually slewing the scope.

If the power to the AZ8 motors has to be turned off to
manually move the scope, will the time and location settings
have to be reset, or will the mount remember its place in
the sky when power to the motors is restored?
?
Also, if using my current refractor (Televue NP 101)
weighing when configured at the most about 18 pounds (likely
less), will I need a counter weight?
?
Finally, if I opt for the dual sided version of the
mount, can the saddle on one side be removed and the
lightweight system with 5 pound head be user installed in
lieu of the saddle?
?
Thanks for any answers and insights in helping me to
decide whether to purchase this mount. ?-- Russ

Re: AZ8 with Gemini 2 and go-to with servo motors
Why not just call Losmandy, the best time to speak to them is in the afternoon. Their mornings are pretty busy which is why I’d suggest an afternoon call. Generally they can answer pretty quickly.

Hi Andrew, the "unreachable" message indicates that your safety limits are not allowing the mount to reach that object. The usual suggestions (test all of these after you connect your PC to the mount):
?
1. That the safety limits are set correctly
2. Start up in proper CWD position using Cold Start -- safety limits position is relative to CWD
3. Make sure your mount is configured with the correct date, time, time zone, and geo location
4. Correct mount type is selected in Gemini
5. If all of these don't help, try resetting Gemini to HGM Defaults, and then do a Cold start and set all the settings again. Try operating the mount without the PC being connected, see if that works.?
?
Regards,
?
? -Paul

Some ideas - make sure your geo location is correct, double check your time zone is correct, check your horizon limits in your imaging app are not set too high, recheck your mount safety limits including your western GoTo limit.
?
Good luck,
?

Dear fountain of knowledge,
I have been having the following issue
the g11 will not goto anything on the southern part of the sky, "says unreachable"
the following has been done
gps?
Polar align?
plate solving
all time date setting ok
point to anything west of the sky perfectly
balanced
I have 2 g11 and the other is perfect
I am stumped?
I'm in uk 51 degrees
went to m51 perfect
went to Mars perfect?
asked to go to orion or m45 and unreachable comes up, Any ideas at all ??

I think you need to install a network analyzer on your PC, and check to see if you see the Gemini on the list. Take the IP address of the Gemini, and insert it into the INDI driver control panel on StellarMate. Hit set, and see if it connects. I have seen my Gemini change IP addresses, so I plan on giving it a permanent IP address through the hand controller when I get back from out of town.

Your Gemini 2 will only change IP addresses if you allow it to use DHCP.? By assigning a static IP address and unchecking the DHCP box in the Gemini 2 or HC the Gemini 2 will always be found at the IP address you entered.??

David,
?
We have been over this several times before.? GFU works fine and very reliability does what it's supposed to do. I just used the current 1.32 GFU and reinstalled L6.1 and HC 1.63 no problem.? I can look at the HC firmware directory in the Gemini 2 and see that the file is being loaded into the right directory by GFU.? This is the memory address that the HC controller chip looks at when it is powered up to upload the code and execute.?
?
We know it works correctly.so if you are having an issue with it you probably have some other issues.? Loose uSD card, dirty connectors, out of spec uSD card, poor Ethernet cable etc. etc. whatever it is it isn't the GFU.? These aren't the droids you're looking for, move along.?
