I have seen the EMC report completing a block in less than 0.005 seconds
but somewhere in the range of 12-20 bps is more the norm.

hexapod to run it at more than 90 ipm and completed the program in under 3
minutes. There is just to much drag on the sherline dovetails to do that
kind of speed without bigger motors.
