Note that after first run your mount remembers 3 alignment points (based on 3 resolved captures), next you adjust the mount manually with screws, so these alignment points are not valid anymore, but probably are used in the next run of the procedure. Can you check on your mount's Align tab how many points are used before the second run? I believe it might be the root cause of this issue in some circumstances. In such a case it's enough to clear all the points before the second run.

Hi! (first post!)

I've been toying with PAA, CCD Simulator and Telescope Simulator from the git repository and after completing the process I always get about 5' 40' - 5' 50' of PA error. In fact, the same behaviour can be seen in Jasem's video (watch it from 5:10 onwards):



As you can see, there's a PA error of 5' 41".

In my mind, both CCD Simulator and Telescope simulator should be "perfect" and have 0 PA.

Is there a bug somewhere? am I worrying too much?

Thank you!

No, the simulators have some error, this is normal.

Will this tool work when you can't see anywhere near either pole?
I live right on the equator and both poles are obscured by 10's of degrees.

I highly doubt it would do any good near the equator... I mean what folks on the equator use to "polar align"?

???
I’m on the equator and I need to polar align.

I know :D

I meant, what is the usual method employed by those near the equator given that the poles are near the horizon?

The only way is drift aligning.

So I have been using the CEM25's built-in Polar Alignment iteration routine, which is the only way to align from the equator.
It works, and just requires me to flip back and forth between two stars for ALT and AZ adjustments.
I cannot see any stars within 20 to 30 degrees of either pole. Will the EKOS polar alignment routine work in such case?
I have not tried myself at night as we have had nasty skies all week.

You could perhaps use the older (legacy) polar alignment helper. It's directly below the Polar ALignment Assistant tool.

I would be highly interested, if this worked - because nevertheless I am living at 48 deg north, I don't have a view to north from my balcony ;-) So without using a guiding scope it is really really problematic. I think, this is a scenario, which a lot of people might have. Or think, if you are in the mountains or have trees to the north.
