Re: DEC axis not moving in certain position. Belt slipping. #EXOS2

Peter Danek
 

Hi Bob,

have you seen my video? I will try to do another one to explain it more. I have seen your document before I posted this and I exactly know where the problem is. The mesh is too tight and the worm is not moving when it is near the clutch. If the worm is in the opposite position down from the clutch it is loose. When I lock the clutch the cylinder with the mesh inside moves up pushing on the worm(see the video).

It doesn't seem right to me. There should be no pressure after locking the clutch.

Re: DEC axis not moving in certain position. Belt slipping. #EXOS2

 

Peter,
 
Sorry, but I don't understand your problem statement.  Are you saying that the DEC axis is binding in a certain position?  Clutches should always be on, if the mount is under power.  
 
If that's all it is, and your scope is reasonably balanced, then all you likely need is a bit of an adjustment.  There are not a lot of moving parts in these mounts, and it is not unusual for some owner adjustments to be needed from time to time. 
 
If the motor is running, the set screws on the two pulleys are snug, and the belt is reasonably tensioned, then the worm gear will be driven by the large pulley.  If the worm is not moving, then the most likely thing holding it back is a too-tight mesh (binding) between the worm gear and the ring gear that surrounds your axis.  This can happen, because the clearance between the two gears is fixed, but the two gears are not (and cannot be) perfectly round.  So the goal of adjustment is to achieve the smallest amount of clearance that still avoids binding on high points between them. 

I don't know what an ES pre-delivery test of the mount would entail, but if bind points occur, they will be at particular locations and there's no predicting whether a short test would actually traverse a given bind point and reveal such a problem.  In any case, if all that's needed is a gear mesh adjustment, that's pretty straightforward.
 
If I've understood your problem correctly, then the doc in the link below may help you, with this and perhaps other things as well.

Hope this helps...

Having the same issue on Samsung TAB A (2016) model SM T585
which runs Android 8.1.0 (Oreo).
Last and latest system update 20-11-30.

I was happily using the app 6 or 7 weeks ago (early Feb.).
Got the scope out 21-3-15 and a "...has stopped" message popped up when I selected M42.
Further investigation showed only Solar System objects can be selected successfully.
Painstaking deinstallation and reinstallation of app ad DB makes no difference.

I await news that this issue has been addressed and solved.

Update to: https://espmc-eight.groups.io/g/MAIN/topic/exos2_working_few_seconds/80714857?p=,,,20,0,0,0::recentpostdate%2Fsticky,,,20,2,0,80714857

Thank you ES Germany for solving my RMA claim. I have received a new PMC 8 unit and it is working as expected. But, I never had such bad luck as I have now.

Because I can now control the mount I found a big problem with the DEC. When slewing and the worm/motor is near the locking clutch, the DEC stops to move and the belt is slipping. I noticed that when the worm/motor is near the clutch, and I lock/unlock DEC, the big wheel of the worm is moving. It is also impossible to move the wheel of the worm near the locking clutch when DEC is locked. However, I can move it if it is the opposite of the locking clutch.

It seems like when I lock the DEC the inside parts move. 

I can make a video of the problem if it is not clear to understand.

Is it something I can adjust or I'm looking at another RMA process? :(

Hi all, thought I'd post this as I've been trying to learn to take pics for 6 months now and after what feels like a long haul this is really the first one I'm quite satisfied with for the level of equipment I have. Hope you like it.

It's M51 - The Whirlpool Galaxy.
60 x 120sec lights @ ISO 800
20 x 120 sec darks
No Bias, Flats etc. I tried with those and they didn't seem to improve anything, so I left them out of the stack.

Location: near Alicante in Southern Spain

Equipment used:
Explore Scientific EXOS-2 PMC-Eight mount
Skywatcher 200DPS Newtonian telescope
Nikon D5200 DSLR unmodified
Orion 50mm guide scope
Orion SSAG guide camera
ZWO EAF focuser.
Imaging Software: KStars / EKOS / INDI

I forgot to add that I am using the ES ASCOM driver and the latest firmware update for my iEXOS-100 which increased 
the motor current when slewing but not while tracking, I do know that the goto results are excellent now !!

Hey Guys,
I just stumbled upon this Topic... My iEXOS-100 mount has always done this also, I have just gotten used to it I guess but
if there is a fix for it I sure would like to find out about it.
FYI, I control my mount via ASCOM wireless or more recently an ASCOM serial connection.
Seems like it would help on PHD2 Guiding, the best RMS Error I have seen is around 1.18" I attached a screen shot of one of my
last imaging sessions.
I would appreciate an info on this.

Hi Sean, welcome aboard and I can assure you that I too am having exactly the issue as you. I have 3 tablets, 1 of which (my 1 year old Tab A ) doesnt open the latest database from the latest app at all. Mysteriously  my two older Tabs open the data base but with the exception of the Solar objects (which are functioning) any other object I select causes the app to crash...... Tyler (of the ES customer help centre and another very helpful chap) have been very kindly scratching their heads on this for at a week now).
I'm sure there will be an answer to this conundrum but at the moment not so.
Kind regards, Brian

Here's an image that shows the correct order, based on the engineering drawings.

I've asked that the order be stated in the iEXOS-100 manual. The list of washers is there, but the words do no state that it is the correct (or in this case, the incorrect) order.

 



The order
1 -- thin washer
2 -- needle bearing
3 -- thin washer
4 -- wavy washer
5 -- thick washer
6 -- thick washer

The clutch knob would be No. 7.

Hi Pete, I've tried downloading via my PC and directly to my tablet several times now and still not able to get the app to open the database..... I've now got an sd card reader which Tyler recommends but this is the first time I've had a problem with the database, apart from my very first attempt a few years ago when I was not organising the folders correctly.
I'll report back when I have used the card reader.... If this doesn't work I will conclude that maybe the sqlite file is corrupted.
Thankyou for helping, kind regards, Brian

For some reason the updated version of ExploreStars, works fine, until I try and select an object from the catalog.  Any object I select my device tells me there was a problem and the app crashes.
I have uninstalled the ES app and DB completely from the tablet (Its a standard Android tab 12 months old now) it was working swimmingly until it autoupdated the app :(

Anybody have any ideas? Or do I need to reset the whole tablet and reinstall and hope for the best? 

Thanks,
