So you had the same problem with the motors removed?

My strong suspicion is that the worm mesh is too tight on the DEC axis.

?

As an initial test, remove both motors from the mount and run your test again.

?

Let us know what happens.

Hi,
I remade all soldering of din plug on the mainboard and verify visually all the others. looks good.

After that mounts works well for 10mn.?
Then I had again both messages?
back from powerfail
DEC LAG

Try with another 13V power. .. worst (problem appear much faster)

Then back on the main power and increase voltage from 15,2 to 16v
Got RA lag message only once then nothing for at least 30mn

something in the power rail ???

thanks erwan

Here is an update on where I'm at. My setup is a C11 HD Edge with a Losmandy G11 mount with Gemini 2. Love this thing. It is housed in a shed with a roll off roof so I can leave it setup.?

I have ASCOM and Gemini Telescopt.net setup and talking on my laptop. Today I installed PHD2 version 2.6.11dev4. As mentioned my laptop only has two USB ports. One is connected to the G11, the other to my ZWO ASI guide cam. Both connect in PHD2. I'm as far as I can go for now, as I'm in the house with just the Gemini 2 box off of the mount and the ZWO camera. Next step is to go out and put the stuff on the mount and try the guide camera Calibration in PHD2. But we have 10 inches of snow on the ground at the moment. I live in the high desert in Oregon.?

I know now I need a USB Hub of some sort. Thanks for recommending the Pegasus Hubs. I think I'll go with the Pocket Powerbox gen 2 for now. The Ultimate V2 is almost twice as much. At the moment I don't have Due Heaters or cooled cameras that need 12 V DC, but I will in the future.?

Next, I want to setup a network to connect the telescope to my PC in the house. I have a CAT6 Ethernet cable run out to the observatory, which is about 150 feet from the house. Actually it runs to my shop first where there is a Router, then out to the observatory. So the next thing I'd like to figure out is the best way to connect it at the scope. Something like the Mele mini PC or Intel NUC. I'd like to stay Windows based, I don't know Linux. So if I'm thinking about this right, I would have the Pegasus Powerbox to use as the USB Hub, have USB hub connect to the mini PC's USB, have the mini PC setup with ASCOM, Gemini, PHD2, etc, and use the mini PC to connect to my network via the Ethernet cable. Is this how people do it ? Since my goal is to eventually run the scope from in the house, I have decided not to go with a ASIAir Plus?setup, as it sounds as if your still outside controlling things via your phone, iPad or tablet. I don't know if you can connect ASIAir to a network via Ethernet.?

As lastly, I'm bewildered by all the Astro programs out there and how they all fit together. I'm starting with PHD2. But then you have all these things like NINA, SharpCap, Stellarium, and many many more. What is a reasonable software suite to go along with PHD2 ? It seems NINA is one. Besides guiding, I will want things that help with polar alignment, focusing, plate solving, image scheduling, planetarium, etc.?

Yeah. "Near" in terms of metal objects near an antenna is generally regarded as 1 wavelength of distance. For 2.4GHz wireless, that would be around 124mm. 59mm for 5GHz wifi.

So, given the above:
- mount does not flip even though it should
- manipulating limits does not help?
- happens via usb or ethernet
- happens even when not running an imaging application
- happen after testing a variety of cables and laptops
Does this imply anything regarding my gemini unit ?

Lenova Ideapad Yoga 13. It has two USB ports, but my mouse uses the 2.0 port. Only the 3.0 port is available.?

I bought my Losmandy G11 w/Gemini 2 in 2018. This is my first goto scope. Been mainly using it for visual and some planetary imaging, but now want to get into DS astrophotography. I have two cameras to use.?
Canon 6D? SLR
ASI462 MC.?
I have been researching setups. Been reading a lot online and watching YouTube videos. I could go with using PHD2 for autoguiding. I have started setting this up on my older Lenova laptop this week. I have ASICOM 6.6 installed, then installed the Gemini Telescope.Net web server. Next is to install PHD2. But I only have one USB port available on the laptop. So now I can see I will need multiple USB ports to connect things up (Mount, main camera, guide camera, and in the future a filter wheel, auto focuser, etc). One option is to get a USB Hub which should solve my problem for now. Another option I see people using is a Mini PC to connect all the equipment, and then WiFi that to their laptop. Another option is to use ASIAir Plus to connect up all the equipment which then uses WiFi to your phone or iPad or tablet.?

So should I just continue setting up PHD2 ? This should get me up and running. I can use the ASI462 MC for the guide, and the Canon 6D for main camera. Then down the road add a ASI120MM mini for guide, and use the ASI462 as main. And further down the road get a Cooled main camera.?

I do like the ASIAir Plus setup though. All the features and ease of use in one box. I understand your limited to the ZWO product line.?

While I have a fair about of $$ in the C11 / G11 scope and a lot of TeleVue eyepieces, I'm trying not to break the bank on my camera and autoguiding setup. Start small then upgrade later.?

From 1980 to 2018 when I got the C11 / G11 I was using a Meade 8 inch f6 Newtonian. Used to do astrophotography with it using an Olympus OM1 35mm film camera. Glad those days are over.?
