sorry to revive this old thread, but i wondered if there are any guides yet?
I just recently got an AZ-Eq6 and had movement in RA and Dec, so that i could rock both axis a little bit back and forth..
I did read this thread multiple times and i also check out the guide at astro-baby for the eq6 for help.
The DEC movement i could get out by adjusting the two torx screws, however with RA seemed much more difficult.. It was either rocking, or there was binding. After loosening up the worm-gear (behind the black cover) a bit, it seemed to adjust a bit better, but I'm somehow still not really happy with it.
I need to wait for clear skies, so i can test how it's performing now, but i'm thinking of taking it apart for cleaning and then re-greasing and for this a write-up would come in pretty handy.
