I must be missing something here, or perhaps something is being lost in translation.Not correct. Maybe the animation is not clear enough here, but the front standard is only used to set the plane of focus before you start stacking. It doesn't change during stacking.If I understand correctly, the animation is showing that the angle of the plane of focus DOES change as you move the rear standard.

The animation very clearly indicates that with the front standard fixed, when you move the rear standard the angle of the plane of focus with respect to the subject changes.

Allow me to ask the question once again.
If you apply tilt and swing to the front standard, and then lock that down, as you move the rear standard in order to create a focus stack, does the initial angle of the plane of focus change, or not?
Everything I have been able to read on this subject says that yes - it does.
The workflow for your product would appear to be the following -
1. Set desired tilt and swing on the lens axis to get the plane of focus where you want.
2. Lock the front standard.
3. Move the rear standard in order to create a focus stack.
My understanding is that when you move the rear standard, the angle of the focal plane with respect to the subject will change. I.e. In the example I provided above, with your solution, I would start with the focal plane aligned with the top of the movement of the watch, but when I get to the end of the stack, the focal plane will no longer be aligned with the bottom of the movement.
Am I correct or not here?
Kind regards,
Gerald.
