Resolution Setting
Steve, Do you still recommend the Resolution: 0.2mm for printing all the clocks?? I just realized I've been printing everything in the default resolution of 0.012mm and was wondering if that was causing some of my problems.

The clock being functional except for the hands moving is likely due to the friction clutch, or more likely excess friction after the friction clutch. Parts of this video might help: https://www.youtube.com/watch?v=deW7OsjY-xQ
SP7 with a second hand requires two gear shafts printed as tubes that need to pass through other printed parts. This doubles the chances of a burr or oval shaped hole causing binding. The other risk is the frame pinching the stack of gears in the central arbor.
The resolution setting is something that I have never touched. I assume the slicer will default to the most accurate value supported. The default of 0.012mm for a Bambu printer seems perfectly reasonable.
