Sorry for being so long but I wanted to explain my case.

As far as tracking goes, if it slews, it should track. The batteries should be fine. Can you see the shaft between the drive and the mount? Mark it and see if it moves at all. Often if a drive won't track, a lock or clutch is loose and slipping. It could even be a set screw that is loose.
I would try to determine if the drive output shaft is turning and then either look at the mount or the drive accordingly.

I am looking to track the sun, I suppose sidereal rate would be the best for that besides the fact that the DD-1 does not give much of a choice. The setting is either 1.5, 2x or 32x, and that seems to be for slewing. Does anyone know any more about the DD-1 capacities and how it can be adapted to the sun, moon and planets... or if there are other options out there for the super polaris mount? Does anyone know if the D3M controller is much better.

or rather.. 7.5 - 12V, the battery pack it comes with is 9V.
The most common source of this problem is slipping of the spur gear that's on the RA worm.
on my Vixen, I noticed that the RA shaft was 6mm... but the bore in the spur gear was 1/4" (6.35mm) - I had to torque down the grub screw in the spur gear really tight (and add a shim) so it wouldn't slip.
this shows up at tracking rate, but at 32X you can't see it because the gear turns fast enough to take up the slip/slack almost immediately.
