Well, no. Both the Mesa and Pico Systems boards close the servo loop in
the PC, at
least when using EMC2.

Well, even still, if you are doing close to 1000 vector segments per
second, that is
a really hard thing to do, and it may be more due to a poor G-code
program in many
cases than an actual need to break the path in that many segments. I do
have a torture
test that I set up for EMC2 to find out how many G-code blocks it could
handle.
It consists of a 3" diameter circle broken into 10,000 G01 vectors. It
handles it
in about 13 seconds, so better than 750 vectors/second. That test was
performed on
a 600 MHz Pentium III, so it will do even better on a faster computer.
