Re: PHD2/G11T connection problems
Hi Brian, ? Type was set to G11T when I received it. I thought it should have been changed automatically too, but it wasn’t. I don’t recall if I tried setting it to another type and then back G11T or not. I might try that just to see what happens. ? Larry ? ? Hi Larry >>>The only issue I had was changing the RA tooth count Default? from 360 to -270 for the G11T. if you choose G11T from the Type screen, it should set the gearing correctly to -270 ?

Re: Counterweight bar safety screw
I never heard of nor his (her?) products before. (Sorry. But not too proud to show my ignorance.)
On my mount the "toe saver", as I often here these referred to, is the fairly basic and substantial Thumb screw with a 3/8" Allan socket stem screw, and a 3/8" fender washer.
It's difficult for me to see where that could be improved upon, except for personal taste.
While I admittedly have a smaller imaging telescope, and lesser needs, I found my ideal solution in the RAEXT and never having to remove my counter weight from the shaft. I can transport the entire Dec assembly as one of my "chunks".
(As I move my equipment out and in routinely.) By using the RAEXT, I never need to move or remove the counterweight, and the assembly stays in balance.
I can understand where the winged supplied "toe saver" might not appeal to all. Have you considered replacing the stock offering with an or hand screw? One of those could be a custom alternative.
Two ways I know of to remove the broken stem:
1. Drill the remaining stem and use an Easy Out to remove the broken end.
2. Use a left handed drill (Harbor Freight, or McMaster-Carr) to drill into the broken stem. The nature of a Left Handed twist drill often removes the broken bolt end. (Lefty-loosey)
I would recommend a machine shop, or friend with a metal working lathe be sought.

Counterweight bar safety screw
I need to replace a broken safety screw. It seems that the Robin Cassady product is no longer available. Are there any (better) options other than stock?

Right now I'm thinking that just cleaning the pads has made a world of difference.
that doesn't surprise me, good news
>>>I don't have a way to ensure that the nut is the same tightness, other than "hmm that seems about the same".
if you are continuing this into the future, maybe a couple pieces of tape, one on the clutch knob and one on the axis, where at least you can line up the tape points. Figuring out the same # of tightening revolutions should be easier
I don't have a way to ensure that the nut is the same tightness, other than "hmm that seems about the same". I was thinking of 3d printing a part that I could clamp to the tightening nut and attach the torque wrench to that. I would of course be careful not to over-tighten the nut -- my whole thought here is that too much pressure on the bearing may cause it to roll unevenly.?
Right now I'm thinking that just cleaning the pads has made a world of difference. I'll take the scope out tonight and see how it goes. If my guiding spikes are gone and I can get those great images again I'll probably put this stuff on the back burner.? There's only so many hours in a day to obsess over this after all!

Re: PHD2/G11T connection problems
I tried an Ethernet cable, and it didn't work. I re-tried the USB port, but this time I did a mount setup which a got with the little black button on the left of connect/disconnect button. I put in some numbers, tried connecting again and it worked with the
USB port. So far so good. Thanks?for the reply!

I would suggest using Ethernet. All the setup instructions are on the Gemini-2.com website. Worked for me first try.

Are you using PHD2 with the ethernet port or something else?

PHD2/G11T connection problems
Hi everybody. I have been using my new G11t for about three weeks, but I haven’t tried autoguiding with it yet. Today I plugged in my mount to my PC using the USB port on the Gemini box. I get a message telling me that the system was trying to connect to the mount but it never does. I did download the Gemini mount ASCOM app, previously. At this point I have no idea what I need to do to get the computer and mount paired up. Any help would be really appreciated.

Re: Options for software control of Gemini 1 (G11)
I use Ekos/Kstars from Indilib.org too and am very happy with it.? It integrates a whole bunch of functionality including dome control of your observatory, planetarium control, autoguiding, alignment, plate solving, multiple configurations.? It is a one stop shop free of charge, and can even run on a Pi 2B (client and server) controlled remotely.? If you need to transfer images and if power is no issue you may want to get a Pi 4B.? It also has an OnStep driver in case you want to build your own Goto controller, which I did (and happy about the outcome).? But Ekos supports the Gemini too IIRC.

Lithium is the worst grease for the mount, it gets hot and drips and runs, it gets cold and stiff , it also dries up and leaves hard clay behind. Buy a true synthetic based grease with Teflon, I like SuperLube with Teflon, it is the best stuff out there IMO and has the lab tests to prove it. Here in the USA Amazon has tubs of the stuff for $10 and is lasts forever. I have been giving blobs to my friends with Losmandy mounts in ziplocks and have rebuilt about a dozen friends Losmandy G11 and GM8 mounts using that can and I still have 2/3 of it left.?

ah okay thanks
how do you ensure you are hand tightening the same amount?
[Edited Message Follows]
This is how I used the torque wrench:?? So now I have a number that I can look at to see if my clutches are slipping and if it's time to clean them. I can also note down the torque numbers on good or bad nights to help understand how the clutch tightness affects guiding.?

He just wants his own telescope!?

Wow! That’s scientific!

I had bought the Losmandy nonslip clutches, which seemed to achieve the desired outcome. However, while recently doing a bit of maintenance I seemed to have misplaced one of the clutch pads. Chief
suspect is my wife’s dog, which has probably hidden the clutch pad in its stash somewhere. Faced with long delivery delays during the COVID-19 pandemic, I decided to improvise. My wife suggested cutting out the shape of the clutch pad from a pastry rolling
mat. I did and it seems to work quite well, although it’s only on the Dec axis. The dog has resumed its status of being “our” dog.

I'm not tightening. I'm measuring how much torque it takes to turn the shaft before and after cleaning the clutch disk. After cleaning the disk the shaft is roughly twice as hard to turn when lightly tightened by hand. In each case I only
tighten by hand.?

I use lithium grease only for the worm & gear lubrication.
No problems so far.

Hi Jamie
please avoid tightening with any tools - you really should not need to do that.?
it sounds like you more need to just clean the clutch disks, which is a good idea from your description
Thought I'd give an update.?
So I got the alternative clutches, and tried one in the RA. Hard to tell if it's better or worse since I accidentally dabbed some lube on the pad, and it's not plastic, so I don't know if I was able to clean it -- Doh!?
Either way I was able to guide pretty well last night. I think that I need to tighten the RA more with the different clutch (lubricated clutch that is...).?
I just took a look at the DEC clutch, and lube has definitely gotten to that one without my help. I'll clean it up and see how that works. I also got a 1/4" torque wrench, just to see if I can detect any better or worse guiding with different tightness of the clutch.?
