Re: FS: Gemini-1 and deluxe hand controller
Naturally, a 2am, I missed the fact that the hand controller is not connected. Sorry for that error. ? But I'd still look for corrosion at the hand controller socket, and the G1 board. ?

Re: PEC in Gemini 2 vs in Gemini 1
Hi!
Thanks, that is helpful in clarifying how the PEC works, great! I'm actually considering an upgrade from G1 to G2, that is why I'm particularly interested in if that would add something to the PEC capacity. THis is not to say I'm disappointed with the G1 PEC - I'm just about to start using it...:)
Magnus

Re: PEC in Gemini 2 vs in Gemini 1
Hi Magnus,?
I can't comment on any difference between G1 and G2, but here are other comments.?
You must always park your mount...that's the only way the Gemini knows the worm rotation angle. ( The same is true for other mounts like the older Orion Atlas. Some mounts now have permanent PEC (PPEC)...with a detector for the worm position. ?)
The SRAM stores the last worm rotation index, so even if you lose DC power, or you move the RA by hand, there is a good chance to still have the Gemini know the PEC to apply. ?
If you turn the worm by hand, that info is incorrect.? Or if you switch Gemini units,...there is no way for the new one to know that angular location (if you have multiple Gemini units....! )
The Gemini can record the corrections generated by an autoguider camera. ? The manual says you must use the hand controller but this is not correct... just point to a star near the meridian/equator, then turn on, say, ?PHD2 autoguiding, and then turn on the Gemini to record PEC.? It should work well. ?
There are options to add and average additional runs, to smooth out any glitches.? When you do that, the Gemini will wait until the start of the next worm cycle. ?
When done, the Gemini has the capability to use its PEC, but you must tell it to do so...it defaults to "PEC OFF".? The Gemini.net applet has a checkbox to automatically tell Gemini to use PEC. That is a nice feature if you are connected to a PC.?
Hope this helps, Michael? ?

Hi!
Anyone here who can clarify the differences in PEC handling and capabilities between Gemini 1 and Gemini 2? There is some PEC functiionality in both as I understand it...
Also: as I understand it PEC works with the Gemini even without encoders, right? How does that work, how can the unit know the position of the worms....?

Rob,
I've had pretty good results with a virtually new Losmandy G11 which sat in a closet for 14 years before I bought it a couple years ago. From a 15 year old virtually new G11 #492 digital drive system to a current spec Losmandy G11G and a few iterations in between I have had nothing but pleasure in learning and using Losmandy's mounts. I got reacquainted with Scott who wa an LAAS member back in the day and have made new friends at Losmandy (I live nearby) and made other friends of local Losmandy owners and a few in online groups. It's a fine and creative group with a lot of what people used to call American know how.?
I'm pretty happy to know that American know how still exists out there if you look in the right places. Made in America can still mean exceptionally good products and that products can be made and sold at competitive prices. I say this knowing that you can buy mounts from American companies that are made in China with similar features at similar price points. But having owned and reworked more than a few of these Chinese made mounts I know there is no comparison in the build quality or support of these products.?
Ross, the newly redesigned Losmandy OPW design is probably now just as good as the Ovision OPW it's certainly more consistently good than the Ovison OPW has been if the many reports from Ovision owners having to send their Ovision OPW back for replacement is any indication. My G11G as the tucked motors and RAEXK installed and yes, you do want these new features along with the new custom cases for each half of the mount head Losmandy will be selling soon. You will have two custom hard cases each with a hard mount in the case to clamp the RA or DEC half directly into the case, each weighing about 25lbs,. The counterweight and CW shaft case will be the heaviest part to transport. No more motors hanging out requiring extra deep cases to safely transport the mount!?
I love a good feel good post!
Chip ?? ?

Agree! ?My G11-G2 is working very well - far exceeding my current capabilities! ?I've been into astronomy and astro-imaging since the mid-50's. I recently had cataract surgery in both eyes that has given me back the stars! ?My G11 is getting a lot more use now! Dave...
|
Haha, I think my current one, the last in a long series of newer & newer G8's, G-11's, has been running for at least 3-4 years now with barely a hiccup electro-mechanically and pretty darn good for the Gemini2OS also! A big help has been one Ovision, 2 Maxon's, a nicer cradle and either of AstroPhysics portable piers.? Looking forward to tucking the motors and the 2piece head, one day... Ross

Rob,
I feel exactly the same way about my G11 too. It performs flawlessly as my astophotography platform.

Re: GM8 Bore Trueing & Bearing Replacement

Re: GM8 Bore Trueing & Bearing Replacement
Hi Michael,?
What you described is correct (Sorry for the long windedness). ?The bearing housing appears to be machined correctly (though I didn't disassemble the pressed assembly). ?I believe it would be very difficult to seat the bearing in the housing incorrectly, without damaging the bearing itself. ?So the bearing is seated correctly but the bearing housing was not seated correctly in the main bore. ?I meant to take photos along the way, but I have so little free time, I was more interested in completing the repairs vs. documenting the process. ?
Using feeler gauges (and confirmed with my digital height gauge on a granite block) I was able to determine which side of the housing needed to be pressed to be seated fully. ?So I located the highest point and used a wood block (to prevent damage) and tapped the block on the bearing housing. ?A couple blows and it was seated fully. ?I reconfirmed with additional measurements. ?
Unfortunately and rather disappointingly, ?Losmandy was not particularly helpful in determining the cause or working on the repair (other than replacing the main worn shaft). ?This was a bit out of character, from my past encounters, though this is the first (and probably last) time I've ever returned anything for service. I feel like they are just completely underwater with these new mounts and don't have the time to support customers with a problem like this. They also must have felt that it was adequately free, and returned it. ?But depending on how the worm wheel was rotated and where the clutch knob was tightened, the axis would seize-up nearly solid, which they must not have experienced. ?I shipped it the second time in a fully seized state, so they could hopefully see the problem. ?The mount in this state may not have stalled the motor, but certainly would not have guided correctly. ?It probably would have been fine for visual though.
Your last statement is also correct. ?There are a couple things at play here. ?Looking at my photo of the DEC shaft, it is clear now that the bearing was seated at an angle. If either housing is not seated properly, the shaft is not going to ride properly on the bearing needles. The amount of wear on the DEC shaft leads me to believe that this was a chronic issue. ?This may be the first time the mount has ever run true.
To make matters worse, this alignment error is going to press on the worm wheel asymmetrically. ?The worm wheel is now at an angle with respect to the bore/axis. ?The clutch pad will touch one side heavier than the other, imparting an asymmetric load on the worm wheel and the greased bearing bore of the worm wheel. ?I believe this is why it was such an intermittent issue. ?You can imagine that as the clutch is tightened, the worm wheel tries to straighen out and run true to the bore. ?But with axis tilted, it locks up. ?A benefit to a properly aligned bore is that now the full clutch surface is fully seated and requires very little force to lock the axis.
This should be a good lesson to others with binding or intermittent issues with a mount. As you mentioned, check the freeness of axis with the worm removed. You really need to use feeler gauges or precision instruments to measure this, as it's nearly undetectable visually.
In my case, all it took was less 1/4 of a degree of misalignment (about 0.006 difference from one side to the other) to completely spoil the precision of the mount. ? But with everything aligned, it's smooth as glass. ?Should be a good imaging mount. ?I'll post excerpts of this commentary in my website to further explain. ?Once an alignment issue is determined the fix is about 5 minutes, without any major disassembly of the pressed assembly.
A disappointing but educational re-start of my imaging activity (DSLR this time, vs. CCD last time). ?Hopefully this will help others. Thanks for allowing me to clarify and further explain.
Best,?

Re: GM8 Bore Trueing & Bearing Replacement
Eric,
Thank you for that detailed description. ??
The root cause seems from your writeup to be incomplete (tilted) bearing seating into the (correctly) machined sleeve.? So your tool kit and some rubber mallet blows are the solution....if owners feel that binding.
We do not know if the original condition had the bearing seated on a tilted sleeve, because L. re-machined that.? Did they say what they found?
I always thought that binding was primarily caused by the worm to ring gear spacing. I think your analysis say that, in the case of new or used mounts, we first remove the worm assembly and just feel for bearing smoothness first. If that is sticking, it must be fixed before the worm is installed. ?
Do I have this right?
Best, Michael?

Re: 492 drive RA seems to be running too fast
Hi Don,
Thanks... reading (esp at 2AM) was never my strong suit. ?
Bottom line: if Losmandy can supply these 27C64 EPROMs for those with GM8 mounts, then I do not need to create a 2nd stock of them.
I did download the code from my own 27C64 in my G11 492 unit, so I can make up copies for those who's EPROMs die.? But I can't recall reading of anyone having that problem (the 492 using 64kbit memory is a lot less than the 4Mbit EPROMs in the Gemini1, so ~1/64th x as likely to fail, I guess). ??
Stay well all... the story had a happy ending!
