Thanks @geehalel. Do you know how I can correct the mount misalignment (does it need to purge the parking or something like that?)? I polar align (using the EKOS tool) at the start of every session, so should that not align the mount driver correctly too?

I've just done some dummy runs tonight, at 0.10 & 0.20 after HA, and the timer correctly shows when the flip should happen, the designated time passes, the status just changes to "Meridian flip planned..." & nothing more happens for a good few minutes after that (I stopped waiting after that). <This is a difference from the other night when it said the flip had actually happened>

The problem is that at 20 minutes of misalignment, the flip will happen too late & my main imaging scope will hit the pier and be useless for anything near the zenith. (I didn't use to have this problem so I'm also a bit confused on how the mount could misalign like this).

Thank you for any more help you can suggest!
