Re: Help with PemPro on G11/Gemini
The mesh network may be causing issues
I suggest?you try plugging in the Gemini via ethernet to your main router's ethernet port and see if that works
>>> I am seeing odd behavior when I calibrate via PHD2 -- I typically see erratic movement/steps in both RA and DEC, more specifically, there will be steps that don't move after a guide pulse, surge forward, or even move backwards on both axis. I am guiding using an OAG @ 2800 mm, so perhaps this is due to seeing and/or PE effects. ? Very curious to see if this behavior changes using a direct ethernet connection.
It would be better to see the guidelog than guess at what 'erratic' might mean ;) 2800mm brings it's own challenges re: image scale and if you're fiddling with PEC, if you have enabled PEC but it's not a good curve, it can cause issues as well. No PEC is better than Bad PEC?
Generally the computer-mount comm performance won't be any different in USB vs Ethernet. it's just a 9600 baud connection, very low data flow.?
A couple more data points ...
- I've confirmed that my laptop with WiFi turned off can also connect to my home network via the ethernet cable connected to the Google WiFi unit's LAN port
- I am able to connect to Gemini via a Direct Ethernet connection (same cable plugged directly into computer). ? As pointed out by?Geordan on?this thread, I too can now see the PEC Worm options after connecting via Ethernet. ? What's really odd is that I have been using USB connection nightly for guiding, pointing, etc. ... so seems unlikely that there's an external connection issue that is the root cause of the PEC information not being visible via USB.? That said, I am seeing odd behavior when I calibrate via PHD2 -- I typically see erratic movement/steps in both RA and DEC, more specifically, there will be steps that don't move after a guide pulse, surge forward, or even move backwards on both axis. I am guiding using an OAG @ 2800 mm, so perhaps this is due to seeing and/or PE effects. ? Very curious to see if this behavior changes using a direct ethernet connection.
- Lastly, I re-enabled DHCP in Gemini, powered it off, moved the cable back to Google WiFi unit, power Gemini back on and ... still no connection / no change to the default IP address so this is definitely not working for some reason and appears to be Gemini specific.

Re: Losmandy GM8/GM11 Encoder Kit
Yes, I recently installed them on my G11G, but only so the mount would ¡°know¡± it¡¯s position after a push-to. They work just fine for that, but don¡¯t in any way interact with the standard encoders that came with the mount. They do nothing at all to aid in guiding performance.?
|
Are there any Metaguide enthusiasts among us?? I briefly confirmed that it works with my GM811G, but I have no feel for how it compares to PHD2 (I did only a brief test).? I have already confirmed that PHD2 works well.
I also did a brief PEMPRO session and confirmed that I can program PEC on my new GM811G, although I need to do a longer session to get better data.? Initial results are not bad at all, even from only half an hour of training.

Re: Help with PemPro on G11/Gemini
I'm connecting the Gemini-2 ethernet port to the LAN port on one of my Google WiFi mesh units:

Re: Help with PemPro on G11/Gemini
What do you mean by adapter??
Hi Brian,
I followed the video, but no luck.? I did check that that wireless adapter works to connect other devices in my house to my home network?(e.g., TV)?and I'm using the exact same adapter and cable.? And I've tried the standard unplugging / replugging, power cycling, DHCP is checked, and ensured the WiFi adapter was up before power on Gemini. ??I also checked my the devices connected to my home network and don't see Gemini.
I'm using a Google WIFI mesh adapter in case you are aware of any compatibility issues. ? ?

Re: Help with PemPro on G11/Gemini
Hi Bret
just typing in the IP address isn't going to work. your Gemini isn't getting its ip address from your router, so something isn't connecting correctly
Make sure your router is fully powered on and working before you power up the gemini
we did a tutorial here that walks you through it:
Hi Folks,
I'm trying connect to Gemini via ethernet to see if that resolves my issue.? I have Gemini connected though a WiFI adapter to my local home network, but I'm not able to connect to Gemini. ? When I look at the network settings in the HC, DHCP is checked, but the IP address is still the default (192.168.0.111) ... should this have changed?? I'm trying to connect to Gemini through my browser at at .

Hi Mengan,
These encoders are for use with a digital setting circles computer. They cannot be used for guiding.?
If you have a guiding issue please post what you are using and what the problem looks like and we'll be happy the help.

Re: Delay before N or S movement, not E or W
>>>
I once tried adjusting the TVC value for this very issue, only to discover that TVC only works when the Speed is set to "Guide".
Yes, that's correct
Sorry i re-read the op which I thought was guide mode, but i missed the center part. TVC only affects guide speed

Can you confirm TV works when speed is set to "Center"?

Re: Start up issues after connecting HC to wrong socket
I would also suggest replacing the coin cell in the Gemini-2.? If somebody told me their Gemini-2 would partly boot up and then get hung, that's what I'd think the problem is.? It's possible your cabling mishap had no real effect at all, but the coin cell happens to have run down.? It's the main cause of Gemini-2 weirdness.
I think that if you had killed your hand controller or port, you would not have seen any Gemini menus on it at all.

Re: Start up issues after connecting HC to wrong socket
Jeff crossing Ra/DEC cables is an oldie but a goodie that everyone does, me, more than once. As for connecting to a computer.....? Start at the first page, read it al especially the tutorials and watch the videos and ?? .? There is lots to absorb Many ways to connect, the easiest is thru the "USB B? port" (not the USB A)? and use Gemini ASCOM.??? The preferred way is using the as its much more feature rich.?? My question.....did you try the Serial/GPS port with the HC??? Did it work or is it working with the HC port? You have to get into the web interface first and set the .? If you have trouble look at the videos and or ...yes you need the HC for this. -- Brendan

Re: Losmandy GM8/GM11 Encoder Kit
Mengnan - I believe those encoders are used with DSC devices for visual push to capabilities. I don't believe those are accurate enough to assist in ap guiding. There exist more accurate ones, but they cost significantly more.? -yurij?

Re: Start up issues after connecting HC to wrong socket
At this point I would have no idea how to run my mount with my PC. I have crossed my Dec and RA but didn¡¯t have any issues except for some confusion when up/down turned into left/right.

Re: Start up issues after connecting HC to wrong socket
Maybe if I left off the inexpensive part and just put ¡°money is no object¡± instead? It¡¯s all okay. We generally get what we pay for.

Losmandy GM8/GM11 Encoder Kit
Have anyone tried the encoder kit??
I recently bought a G11G. I wonder if the encoder kit will improve the guiding performance. I'd appreciate it if anyone shares some experiences. Thanks.

Hopefully you have good hand eye coordination??As mechanical things go a G11 is pretty damn simple. We aren't workin' with watches here.
Three years isn't a long time in the life of a G11, OTOH, 30 without service is. There are folks in your club who will be glad to help you get started and experienced hands here to provide advice if you get stuck.
