On another note, I was doing some more investigating last night, and concluded that I don’t have an auto guiding issue at all. For whatever reason my ASIAIR is dropping out the tracking about every 15 seconds. 

This is an interesting problem and I just need to dig in deeper. I’m suspecting a cable issue at this point.

Hello Ram
Welcome to the group. I too am just past a newbie, but still learning
Balancing a mount is not specific to ExosII. There are plenty of videos on YouTube 
I set the mount on a firm location then using a level I check each axis at the legs for level. Make sure one leg with the little black tab faces North 
Then I set the unit and secure. Before installing the scope put your counterweights on make sure clutches are locked first
Now to balance I realease the clutch that allows the scope to fall horizontal to grade hold the scope while doing this. I the using the counterweights balance the scope so it stays horizontal on both sides
Now with the scope horizontal clutches locked release the clutch that will make the scope fall forward or backwards. To balance this you will need the scope forward or back along the vixen mount. Be careful till balanced hold the scope.  You should now be balanced, oh by the way install all your gear on the mount before balancing 
Next step is to polar align. I suggest polemaster or sharpcap these are on YouTube 

Hope this helps

Exos 2gt with PMC instructions for a newbie

Ram Bache
 

I received the EXOS2 mount yesterday with PMC 8. I am very impressed by the build. I am looking for clear instructions on how to balance the mount. Either written with pictures or a YouTube video. The manual I got is not clear. Since I am a newbie and I don’t want to ruin the mount by not doing it right I am looking for help
please can you point me in the right direction

Hey Dino,

this website is amazing for everything ASIair related and will help solve your issues. They have many other posts as well, but I believe this is the article that will solve your current issues, as I was having the same.

Re: PMC-EIGHT

Dino

The motor count settings are the number of motor steps per full rotation of the wheel.  These values are hardware related and should be left as set by the application.   If you change those the mount will lose track of where it is pointing.   The applications make the assumptions that so many motor steps equals so many degrees of rotation.  In the case of Explorestars, ascom or the asiair drivers the steps per degree are known and used to compute sky position.

The number 47 relates to the sidereal rate being employed.  You can alter this number if you wish to make your mount run a bit faster or slower than sidereal.  For example the king rate, lunar rate.   They are all about one count away from 47 which is the sidereal rate.   If you have a g11 this number would be different owing to the drive train.  Exos2 and iexos are the same and require 47 to run at sidereal.

The firmware works fine with the asi air however you probably need to make sure you get the correct version.  Someone that  uses it can advise you, the asi air code is not supported by ES and I have no experience with it.

The thing about the exos2 is that it has dec backlash that can lead to calibration issues for guiders.   So you should adjust the dec axis to have as little as you can without binding.  Robert Hoskins wrote a tuning document that goes into (among other things) tuning up the mesh.   Look for it in the files section of the main or mounts subgroup.  Cannot remember which, might be in both places.  Even when adjusted however many users still experience backlash.  To overcome this we use camera end heavy mount weight bias, and PA error to force dec corrections to be mostly unidirectional.  This works fine unless you have wind or other disturbances that lead to dec guiding reversals.  In those conditions you might notice intervals of dec error with apparent refusal to respond to guiding pulses as the backlash is absorbed.

Re: PMC-EIGHT

Thanks Wes. Actually, I thought I was in the Application subgroup when I posted. My bad.
But now that I have your attention, 🤓, I have a question about the tracking parameters in ExploreStars app. And in the pmc8 tracking in general for ExosII mounts.
I see in settings where the RA & Dec steps (4147200), and beneath that tracking speed and obs size. Could you briefly explain these values before I start fiddling around. 
BTW, I moved my rig over to my Atlas pro mount to rule out any issues w my ASIAIR device and everything communicates fine. So, my issue is now pointing toward why the pmc8 is not interpreting the tracking cmds from it so that auto guide can do its thing.

thanks for help in advance.
Dino

Re: PMC-EIGHT

Dino Monaco
 

Hi guys, 
Just received my Exos2 pmc8 and I’m just getting acclimated to this mount.
 I've been running my ASIAIR pro successfully with my Orion Atlas pro mount for several years so I’m quite familiar with its functionality.

Now, I’m wanting to try the ASIAIR device with the pmc8 mount. Currently, I’m using the correct serial FTDI cable.Ive inverted the chip as instructed.
Everything communicates & performs beautifully; polar alignment,  target location, plate solving. EXCEPT when I go to perform the autoGuiding sequence  in the ASIAIR app. It locates a guide star with the green box,, targets  it fine along the multi stars targets, but then fails calibration.
Tracking shows that it’s  active in ASIAIR app. And tracking rate is sidereal.

It appears ASIAIR is not sending correction data to pmc8, but I’m not certain why. So, I'm thinking it has to be a set up parameter that I’m missing. Or something.
I’m curious if anyone has experienced this issue.
Any recommendations would be much appreciated.
 Thanks, 
Dino Monaco
