I think either direction g0 g1 or g1 g0 matters the same, you either
have to add some clearance (how much?) for the blend or hope the
default is exact mode or add the exact mode where one has a

A tool length and width and shape probe is needed for some types of tooling.
For some a camera can be used but beware of camera optical axis and
resolution accuracy etc
For best quality you need to detect the run out so you know the
effective diameter too.

To bring a vfd to stationary fastest the vfd has to have control to
use the deceleration curve/braking resistors if fitted and used.
Therefore keeping the vfd powered is safer in the initial stop, only
then should it be powered down.
