i have a trocoiddal path straight through a part and would like to "shrink" it to the center of itself to make it tighter in over all cut path

Are you cutting a straight slot? Does the GCode contain Circles/Arcs? What does a simulation plot look like?

The Transform can scale the XY directions independently, but not if there are G3 Circles/Arcs because they would then become ellipses.

Here is an example scaling the X dimension by 0.5
