I suspect you have had a happy coincidence of ratios that make it appear that the vector is being scaled.

If you try this little exercise you should see what I am saying about vectors not being scaled
Run a similar vector and raster engrave job to that shown below in the pic.
I am guessing, because of what you said above, that both of the the circles will come out at close to the true shape.
Then without changing anything, EXCEPT, double or triple the value in "Current diameter (mm)" box. Same material, same everything else.
Re download the job and run again.
I believe you will see the raster engraved circle change shape (scaling changes around the rotary axis) as you would expect.
But the vector engrave circle will remain unchanged.
Hope this helps.

All this discussion has got me thinking I will build a friction roller type rotary, to add to the chuck type I have.
I can see that it is good design principal to have the gearing or ratio match the Y axis. I will do it this way.
What diameter are the friction drive wheels on yours? And space between them?
I see you had some problems with items being kicked out during rapids.
Has experience with your rotary told you this is ideal, or would you make them larger or smaller, if doing it again?
My guess is, larger would be better than smaller.

If I ever build a new laser, I would also build it with mor z height. The current size is a bit tight for doing rotary work.
