NS11 Eq Auto Align Alt Index Question

I'm not sure I fully understand what you seek here, but my assumption is that when you align the index marks on your 'scope's mount, you are suggesting that the "Get Axis Position" does not equal zero, (either for the altitude or azimuth axes).
If this IS the case, the quick answer is that they won't until you switch off. However, when you switch on (immediately) again, both readings WILL have been set to zero.
These figures/settings though, have nothing to do with the EQ alignment procedure.
Forgive me if I've misread your question, but if I haven't, does this perhaps explain ?

Both only suggest a mere alignment of the index marks within the EQ AutoAlign procedure.
Could you therefore let us know more specifically to which model you're actually referring here and also possibly quote the section of the appropriate manual where "Alt=0" is required in the context of conducting an EQ AutoAlign ?

Looking however through the GPS 11 manual, (pages 16-21 covering alignment procedures), I still fail to see any reference to "Alt=0" when carrying out any of the alignment methods. The only wording I saw was within the "TwoStar Align" where it states the HC screen displays "Alt to Index" at one point, which I interpret as, "Move the OTA in altitude to align the index marks".
Maybe I'm missing something obvious for which, if so, I apologise, but here's a download to the manual to which I have been referring. Perhaps you can indicate where "Alt=0 appears ?

2) The Nexstar displays the message, "Set Alt to Index". Use the up and down direction keys to rotate the telescope tube until the index marker that moves with the optical tube is lined up with the stationary index mark on the fork arm.
This suggests manual use to me.
Hope you get it sorted out.

It sounds though from the above, that as a C11 owner, Mark may well be able to elaborate on his post to provide a satisfactory explanation.

If I remember correctly the index marks are just stickers. On my scope my home position was close but the index marks didn't exactly line up ... one came off and was just put back by eye. I seem to remember a discussion in the Yahoo NexStarGPS group about the position of the marks not mattering much. I know that on my scope I didn't worry about the minor miss alignment, I got them close and then let the scope do it's thing. My NS11 usually delivered very good gotos.
A cm sounds like a lot but overall if the scope slews across the sky without problems and gets close enough to the alignment stars so they aren't incorrectly identified it will deliver good gotos, so I wouldn't worry about it.
