TSRobot Posted September 26, 2018 Share Posted September 26, 2018 My azgti is fab for most things including my first time solar tracking today. However when I move the mount manually the azimuth (left right) is always stiff. I have the black screw completely in done. Not sure what to try without returning it or dismantling it a bit.

I had exactly the same problem so I sent it back for warranty repair, after 2 months it came back exactly the same, so I pulled it apart and found the problem and fixed it.

TSRobot Posted September 27, 2018 Author Share Posted September 27, 2018 Seen all the pictures now of how to strip down the azgti and possibly fix it but that'll void my guarantee for sure. Probs have to return it then. Have to email FLO about that. Do they all have the stiffness in manual azimuth movement? Link to comment Share on other sites More sharing options...
axle01 Posted September 28, 2018 Share Posted September 28, 2018 Yeah I returned mine but came back the same, maybe they dont know the problem and how to fix it, anyway I found the problem and fixed it,,,,now no more binding. Al 1 Link to comment Share on other sites More sharing options...
TSRobot Posted September 28, 2018 Author Share Posted September 28, 2018 Working hard to fix it now as per fab instructions. No issues yet. Warrantee void I guess ? All moving smoothly now but will it ever work again ? Link to comment Share on other sites More sharing options...
TSRobot Posted September 28, 2018 Author Share Posted September 28, 2018 (edited) After many attempts I've made a thin washer from a yoghurt pot. This has fixed it brilliantly. Now it rotates in azimuth smoothly 360 degrees as it always should have done so manual use is perfect. Without the washer no matter how I reassembled it it still has a stiff spot. Been tracking the sun to test it. No problems so far ? Edited September 28, 2018 by TSRobot . 1 Link to comment Share on other sites More sharing options...
axle01 Posted September 28, 2018 Share Posted September 28, 2018 Nice work mate, I found the problem was the grub screws. Al 1 Link to comment Share on other sites More sharing options...

All nicely adjusted till I tighten the grubs(for the umpth) time then back to the stiffness each time. Haven't any locktite so thought I'd try some more grease and a washer. All smooth now and more adjustable. Link to comment Share on other sites More sharing options...

bottletopburly Posted September 29, 2018 Share Posted September 29, 2018 I know someone with a brand spanking new az gti , had problem with it jumping , strip it and there was a lump of swarf in the gearing and one of the axis had no grease at all on it , luckily he is more than competent to be able to sort it .

Refer to page 20 my post 486 and read on. https://www.cloudynights.com/topic/586532-new-skywatcher-az-gti-goto-wifi-mount/page-20 Hi - Don't know if it's just me (or my browser), but the AZ-GTi stripdown photos you posted over on CN aren't visible. Any chance you can repost them here or elsewhere? Also, I didn't quite understand the addition of a washer to the AZ clutch mech that's referred to above - was that part of the solution you provided? It's the AZ axis that I'm having problems with - on a brand new mount! Any help advice you can offer would be much appreciated. Skywatcher are not my favourite brand at the minute, I'm also having problems with a Star Discovery mount, but that repair is in hand.

TSRobot Posted October 8, 2018 Author Share Posted October 8, 2018 Hi. Just looked at the CN link and the pictures were there. Those are the pictures and instructions I used to dismantle my azgti. The plastic washer is still working well. My picture is a bit blurry I'm afraid but the washer (cut out with scissors) was so simple to do and I had nothing to lose. Make sure you have a full set of Allen keys and plenty of time. Link to comment Share on other sites More sharing options...
stargazerdaniel Posted August 8, 2019 Share Posted August 8, 2019 Hi. I have the same azimuth stifness problem with my new AZ-GTi. I have carefully read the posts by axle01 and TSRobot (thank you!). So please let me just check whether I have gotten your point correctly or not. As far as I understand from your posts, the problem is not that the grub screws in the locking ring are too tight, but rather that the locking ring itself is pressed too hard onto the dark element below... So that the plastic washer made by TSRobot is effective in making the friction between the locking ring and the dark element below less stiff... Am I correct? Thanks, Daniel 1 Link to comment Share on other sites More sharing options...
AstroNebulee Posted May 7, 2021 Share Posted May 7, 2021 (edited) Just a refresh on this thread. I had binding issues mainly with my azimuth axis was free on a quarter of the mount then the rest binding when turned. So followed these instructions and a video on YouTube to fit a plastic washer out of a margerine tub lid and greased it up with some white lithium grease. When doing the grub screws back up you have to be careful as tightening to much binds the axis so getting the balance is key. Tested and it rotates using the app and so much more free movement. Whilst I was about it I undid the locking ring on the alt axis as this was stiff but not binding and greased this with white lithium grease also. Now both axis are moving so much better can can push with one finger. Whilst fitting the washer I check the meshing of the azimuth axis motor and this was fixed and not working with the spring so left this as was, the alt axis was working on the spring so left as is. If any issues I'll make the spring work on the azimuth axis. It left the factory like this so maybe the fixed mesh on the azi works well as my goto was/is great. Just waiting on clear skies to test it out. Edited May 7, 2021 by AstroNebulee 2 Link to comment Share on other sites More sharing options...
AstroNebulee Posted May 11, 2021 Share Posted May 11, 2021 (edited) Quick update... After testing the mount for tracking last night on M81&82 I found that tightening the ra/azimuth clutch finger tight caused star trailing and having it just bite the clutch gave no star trailing. So I'll open the mount again and adjust the spring tension on the azimuth motor so the spring activates against the worm and not fixed like before, I'll also undo the grubs on the locking ring ever so slightly then I'll be able to nip up the azimuth clutch a bit more, as I think this is where 95% of the binding comes from. But so far so good I think. Edited May 11, 2021 by AstroNebulee 1 1 Link to comment Share on other sites More sharing options...
