I agree with Wouter that balance in both axes should be the goal. I can't fully see your dovetail gear setup, but I'm left wondering whether you could re-distribute and/or dead-weight the dovetail a bit more to achieve balance. The dovetail itself seems symmetric enough; how far out of balance do you think you are in DEC? You don't seem to be carrying that much weight; I would think you still have plenty of headroom to adjust. About the calibration steps, besides the cal plot, you can look in the guidelog (can't remember if you need to enable verbose & file mode or not). The calibration section of the log will show the step size magnitudes. I use PHD, but the internal guider has a similar plot/log
