Re: Why is the push to such high step rates (Grex and Arc100)?

That's cool, I can understand and appreciate that. I also understand
that the cost difference isn't there (between 1 and 20 Mhz) and that
has not been my concern. I was just trying to find out if there is
any practicality to have a pulse stream running at 4 Mhz within motion
control. If there is, it must be some VERY interesting technology,
extremly fast and accurate!

Thanks for clearing that up.
