Dave,
Something doesn't sound quite right to me. Make sure all your grub screws are tight on the encoders. Do you have the encoder mounting kit with the plastic sleeve on the azimuth encoder shaft ? Do a daytime test on a fixed target some distance away. Switch to "mode encoder" and make sure your encoders come back to zero when you re align on the target. There is info in the manual on this. The other thing that you may need to tweak is the "alt ref angle" what do you have this set at ? On my 10" GS dob it needs to be 92.75 deg I would assume your scope would need to be set at a similar angle.You actually calculate this by trial and error, there is also info in the manual on this.
