Where to put the tool setter is likely where it's easiest for an operator to
also access the tool.
I don't know if the CNC router falls into an operation like changing a drill
bit. For most operations one just sets up the tools, tool table for those
tools with the lengths in the tool table. But if you have only one drill chuck
but need to drill different size holes then the way to use Tool #6 (the drill
chuck) is to set the length to 0. The tool change software then just uses the
tool table length to set the offset and the tools are used without ever
touching off.
But with Tool #6 the 1/4" and then 3/8" drill bit are different lengths. So
you might do a tool change to install the chuck and then pause over the tool setter. An
operator then puts in the right size drill bit and the system continues to then touch off
that drill bit but doesn't update the tool table length; that stays at 0. The holes are
drilled and then rinse and repeat for additional drill bits.
Anyway, that’s one scenario.

If the drill chuck is stiff enough, that works well, but I've not found
a chuck that doesn't have a thou run-out sticking as far out of an R8 as
it does, so I tend to use the r8 that fits the drills shank, its
stiffer. This demands you bring the setter into use as there is no
consistent depth stop, at least in the 4 different r8 kits I have. More
monkey business that probably cancels any time saving the tool changer
offers even if it changes the whole r8. So much easier to assemble the
drill in an er32 TTS holder, and build the tool changer to change the
TTS, measure it once and put it in the tool table. That would be valid
till the er32 nut was loosened again at the cost of the TTS stuff.
Another possibility might be to steal the pcb drill idea of a tight
fitting printed ring placed on a bit shank to serve as a depth stop,
that you could put in the tool table.
Methods depend on your imagination.
