Greg, Stuart, Frolinmod, Joshua, CDKPhil, Graham and Paul,
First of all, thank you very much for the posts and the help. I would like your advice at this stage. I have done everything that Software Bisque has asked me to do:
- Adjusted the RA camstop more times than I can count.
- Centered the worm twice.
- Adjusted the Spring Plungers to 2.5 turns and 3.5 turns.
- Made a 95 pt. T-Point Model for Steve Bisque
I have at least spent a total of 30-40 hours trying to fix this $9000 mount, if not more. The ONLY thing that stopped the mount from stalling in RA was adjusting the spring plungers to 3.5 turns. This eases off the spring pressure and the mount functions normally - but I've found, today, that if the spring plungers are at 3.5 turns the RA axis develops about 1-2 mm of play. There is no play at 2.5 turns (I've done an A-B-A test), and the RA axis is rock solid but as I said, the mount stalls with that much spring pressure.

My question is: what should I do now? Should I ask SB for a replacement? Is that reasonable at this stage? In my opinion, easing of the spring pressure doesn't actually solve the real problem it just masks the issue by easing off the force on the worm and it continues to track.
Mr. Patrick Wallace over at SB forums states that my T-Point Model is OK, and I believe him. I believe the issue develops after I wiggle the RA axis 3-4 times (before that, oddly, it's OK).
