Sorry for the late reply. I use android. One issue I sometimes find with PA is that the 'target' at the top of the triangle is off screen. In this situation i have to get PA as close to 'target' as possible then start the process again. Less than ideal...

Thank you for that. Any idea of the update PA error that I cannot seem to find?

Bump. Has nobody any thoughts on this?

I think I have finally sorted the problem out. I found at one point, that when the mount was in home position, in kstars the position was not coinciding with the north celestial pole. I ended up getting the mount to slew to the NCP and set this as home. Crucially, I updated the home position in the INDI control panel and it worked and now slews the correct way. Interestingly, in the past I had tried to purge etc in the EKOS control panel, but the problem persisted. I think that the key was not purging or updating home in EKOS, but in INDI!

I finally appear to have Stellarmate directing my mount properly at last! I have now just started using the Stellarmate app and am gradually finding my way around. I have two questions though:

1. In polar align which seems to work well and quickly, as well as using the visual aid, I use the polar alignment error figures. The text box thaat comes up states 'use update PA error to estimate the remaining error as you adjust the star position'. However, in the app I cannot see anyway to do this, although it is present in Ekos itself via vnc. 
2. I cannot find a way to manually move the mount in the app - surely this must be possible? In EKOS there is mount control that allows directional control, but in tthe app nothing.

I fitted an TRC module into a Flirc case without any problem.

Richard Wesson created a new topic ' Re: ASTAP set up' in the forum. 6 months ago

I am gradually setting up stellarmate (again!) and whilst I have managed to sort earlier problems out, I am struggling with ASTAP. 

I have installed ASTAP onto stellarmate on my Pi4 and have run it as a standalone programme. However, looking at other people's set ups on the forum, I see images of stellarsolver options showing an ASTAP icon below the index files icon on the left. Mine is missing this. The settings are as follows:
Source extraction method: External SExtractor
Solving method: Local ASTAP

On the EKOS align Tab there is no ASTAP option at the botton - only StellarSolver and Remote. 

When I try to point the index files location to /opt/astap it will not load indexes and folder details say 'Dowloads disabled, directory permission issue. 

Consequently, when I run capture and solve I get the astap programme open but it says error accessing file - I imagine becasue it cannot access the index file. 

Any ideas?

The description of your problem matches exactly mine.
In my case it was the longitude that was wrong. The hemisphere obviously also needs to be the correct, and lastly the hour.
I suggest you have it gathering the hour from the system to troubleshoot, but ideally you would get coordinates and time from the GPS.
The key aspect is that if the time or longitude are wrong the calculated Zenith is pointing on the wrong direction.

One more critical aspect.
My DEC always starts with a full rotation Eastwards, regardless where the target is. I don’t know why, but it does once at the begging of a session IF I didn’t park at the end of the previous session. If I park it, it never does that full rotation. If I don’t park it, it always starts with a full rotation (once I start slewing)

Give it a try. Apart from these little tricks, I super pleased with the portability of the RPi.

Tried again tonight. Took scope of mount and tried to see what would happen if I didnt abort go to. I selected Andromeda. It got there eventually but only after going all around the houses on the dec axis as you described i.e. it went pretty much 360 degrees. when I park the mount it then slews all the way back. Obviously, this is an impractical situation. I cannot take the scope off to slew to target all of the time.
What I do not understand is the software knows where thev target is and where the scope is supposed to be going. It will get it there, but only by going the wrong way around. This makes it unusable at the moment. Logs attached again.
WRT PAC I cannot find a way to turn off in the mount drive unit.

Knro,
Thank you for your reply. I have retried with location updated by kstars and conforming to my location i.e. longitude now correct. Still the same problem.

I statrt with scope in home position and the scope location when I slew seems completely wrong. I can even see the cursor of the scope moving in the wrong way. If I click on an object say andromeda galaxy and then tell it to go to, the cursor does not go to there but off in a completyely wrong direction. Logs attached.

Glad you got it working. I checked and rechecked coordinates several times ensuring they were correct. I also ensured that latitude and longitude were not mixed up (as a sailor I am very aware of that!).

To be honest, I have got fed up with trying to make it work and have found dealing with a Linux based system not the easiest - for example trying to run off an SSD which I got working eventually, but only after finding that the drive enclosure I had bought had a chipset that didnt work with the PI and spending several days trawling forums to work out how to do it. Also tried to install a USB wireless adapter - not joy after following various forums to find out how to get it to work.

Have had no feedback after posting my logs and required information other that from you.

Therefore, I have decided to give up on Stellarmate and INDI and go back to working with a windows based ASCOM sytem where at least installing a basic peripheral does not take several days! Am going to sell the Raspberry Pi with Stellarmate and put it down to experience...

I am guessing nobody has any thoughts suggestions based on the logs?

Update, I have purged both park options data and configuration. It appears to park with the cursor pointing at polaris now but when I click on a target and issue a go to it always slews east - no matter whether the target object is in the east of west. You can see the cursor moving and it always heads in the same direction no matter what the target. I have also noticed that if I look at an objects coordinates in kstars and then look at the object position in the eqmod mount control, the coordinates do not match.

A log files from earlier today is attached.

Also to note, when attached to a windows laptop running ascom, this issue does not occur and the mount slews correctly.

Logs from this evening attached.

One thing that immediatley springs to mind is that in the INDI control panel, the EQ coordinates do not seem to coincide with where the scope is pointing. If the mount is in parked position and I sync to polaris. I can look up xcoordinates of polaris but the do not match with this. If I then press 'set' the mount slews somewhere completely different - presumably to where it thinks those coordinates are.

As above I have done the purge all configuration several times. Drive is EQMod mount.
