I have no issues so far with my U1! However, I ran the initial calibration from setup and would like to “fine tune” it while I have some downtime. Is there a Wiki guide, I searched but a lot of pages comes up for ‘calibration’ or a Post for recommended calibration beyond the initial setup?

When first using the machine, at least perform the following calibrations:

1. Vibration suppression
2. Bed leveling
3. Four-head precision calibration (also called four-head alignment)

Additionally, when sending a print, if you’re using a filament from a manufacturer for the first time, you can check the flow calibration option, and the machine will match an appropriate flow rate.
