I'm attaching last night log.? I'm not sure if this is the best I can post, because I used dithering and this makes analysis more difficult.? I'm aware of the machanical causes of all the main spikes in the error spectrum, but what I'm not sure is if the RA Axis could benefit from some loosening of the bottom cap screw, that is, if such loosening could smooth a little the error plot.
Best,
Daniel
