OK, then here are a couple more.  One is feedrate compensation, where
all axes are slowed whenever one axis begins to lag behind.

Another is that reading encoders back to the PC allows for rigid tapping
and lathe threading by very similar means.  A Gecko can't do that all
by itself, except for 1:1 ratios.
