Quote:Then I did a one star alignment. Wow, you are right Andrew. Now my drifts were only in RA. No more inverted "v" trails.
Quote: Now how about the RA tracking problem thats left. How can I get rid of it.
Quote:Is this something in the firmware or motorcards or design that Meades going to have to address or is it mechanical.
Quote: If their are better wormblocks on some models then, Meade please send me one.
I lost count of my scopes. Now I just want mobility. I came, I saw, I bought some interesting accessories, and put names to faces: NEAF 2012, ASAE 2012, SWAP 2013, ASAE 2013.

Quote:Hi Starhawk...Your flustration with this mount is well documented, and well understood.Really, i thought an engineer type would have enjoyed trying to figure out what was going on, and how to fix it.

Andrew buys mounts on based on my recommendations!
Quote:What I suspect you will find is the tracking algorithm is using a set of rates, none of which are the true speed, but they averae out over 10 minutes or so to make it appear like true tracking.
Quote:I'm not criticizing Neilson or Andrew for trying.
Quote:I bought a floor demo CGEM from my local Meade dealer. It was about the same price as the new price of the LX80. It worked (and continues to work) great right out of the (previously opened) box) I was so impressed with this mount that I bought a new CG5 for portable work. The CGEM is a heavy beast and not the best (IMO) for trucking around. The CG5 is fine and is good for visual use, I have not yet tried it for AP, not sure if I ever will.
As I have posted before, I really wanted the LX80, though I knew that 90% of the time I would use the mount in polar mode, I liked the idea of having Alt/Az if I ever used my OTA for terrestrial work. (though there not much to look at in my neighborhood ) I also liked the promise of a guide port and a PEC capability at a bargain price.
Turns out that the mount does not work in the mode that I would have used it, PEC is still broken as we await another software patch and the guide port option may never be delivered though there are some workarounds for this.
Some people like to tinker with their gear, and some people like to take things apart and MacGyver their toys. I confess that I'm in that camp too. But its one thing to take a mount that is rated for 30 pounds and make it silky smooth at 35 pounds with some micro adjustments and better quality grease...
Its another thing to repetitively rebuild a brand new mount without any improvement while you wonder about your OEM warranty. At a certain point this stops being a hobby and is just a point of frustration.
IMO Neilson is way past what any customer should be expected to do. I would have returned the second mount, when I discovered that it was shipped without any grease in either axis...
His "stick-to-it-ness" must be applauded. And we can all learn from his experience.
Quote:The issue is the “pitch” of the worm gear.
Quote:If one is spring-loaded, that could be an issue.
Quote:Gday LeeJay Quote:If one is spring-loaded, that could be an issue. The worm carrier is spring loaded,and its a really BIG spring, with a lot of preload.I am suspecting this is why the testing with a heavy OTAwasnt working well, due to the worm disengaging.Also, with a higher spring pressure ( to prevent disengaging ), the sliding friction goes up and may account for some of the "jerking" seen in the piccies taken at high focal lengths, esp if the worm isnt well polished.It looks like a std 60deg toothform at 16TPIJust need to get the OD of the worm.Andrew
Quote:Well. If I had a chane to get a CGEM for what I paid for the LX80, I wouldn't still be waiting on the LX80. I'll keep my CG5 for portability.I know I wouldn't have had the patience of the early LX80 users but I'm glad thy are still in there pitching!I'm also glad to see that Ed Thomas is going to get a first hand look at,the innards... Even though it is a new mount, I'd add a Supetune kit if it improved the mount.

Quote:Hi Kevin, I'm sorry your having to go through all this with Meade and I hope you get better results with your new mount. As for me, I am really upset right now. I have a mount that is useless to me. I prefer AP and this mount is just incapable at least with more than 10lbs and that's guided only. And at 500mm fl. And just on one persons mount that we know of. I was going to return my mount today and buy the CGEM DX. But this has gone on so long that the price is back up to $2,000. I only have $1,800. like it was. I thought the price drop was permanent since most telescope stuff never goes on sale. Now I am out of luck. I dont want a CGEM and will not buy one. I expected this LX80 to work. I expected Meade to step up and fix this thing. Well Meade we are all waiting. We can't fix this for you. You designed it poorly so you need to recall them and replace the poorly designed wormblock. And fast. TODAY. Or better yet send me the new part. because I am tired of images like this one. And I am tired of doing your job for you. neilson
