... this timing issue is usually solved by waiting half a second or so for the vibration of the mechanical setup to settle. That is: "Move"-"Wait"-"Capture". Actually, due to the delay of the libcamera pipeline, you can already start the next "Move" at the time you are saving the capture.
Also, in a film scanner application, the frame delay stays normally fixed. With a little experimentation, you determine that delay and trigger the camera accordingly.
There is yet another challenge - mechanical vibrations induced by people moving around the room. Depending on your location, even people running stairs a few meters away will introduce motion blur on the capture. One remedy is to use the fastest shutter speed you can work with, another one is described in the Kinograph-forum (https://forums.kinograph.cc/t/shakefind ... ers/2761?/) "ShakeFinder: A vibration sensor for stop-motion scanners").
Maybe you find browsing the Kinograph-forum interesting for your project anyway.
