Hi Sean, you continue to see some strange behavior, so there may be something to the SD card and settings needing a full reset. I wouldn't do it just yet. From your NINA platesolving results, it appears that DEC wasn't moving at all, while RA was correcting properly. Since the original error was fairly small in DEC, the only reason I can think of for DEC not to correct is worm/gear backlash. Let's see if the downgraded L5 firmware will help, but do check what TVC (backlash compensation) setting you're using. That may need to be adjusted when migrating to L6 due the 4x smaller steps with higher encoder resolution.

Paul,
I should point out that since the upgrade I have been getting a click sound when mount moves/stops. This was most noticeable when the repeated plate solving attempts were made in a quicker succession. The sound appears to come from the Gemini box and not the actual motors. Yesterday when I re-uploaded L5 I did do a slew, and did not hear the click.
As for TVC, I don't know anything about this. I looked at the web UI and do see DEC DEC TVC Step Count is set to "5".?
RA Worm Ratio ? ?360
DEC Worm Ratio ? ?180
RA Spur Ratio ? ?25
DEC Spur Ratio ? ?25
RA Motor Encoder Resolution ? ?256
DEC Motor Encoder Resolution ? ?256
RA Positioning Resolution ? ?0.562500" ? ?DEC Positioning Resolution ? ?1.125000"
DEC TVC Step Count ? ?5
It looks like tonight around 10PM CST I should be able to at least test (though not clear enough to image I should still be able to move and platesolve). If the L5 (5.22) I have no idea whether I should attempt to go back to L6 and see if maybe a setting needs change.?
