If you will be using the USC, then the G201 is all you want. The USC
board can put out
all the step pulses the Gecko can handle. The only place the G210 is
needed is where the
step pulse generation technique can't handle the step rate required,
therefore limiting
the feed rate. Software step generation limits the speed at some point,
anywhere
between 25,000 to 100,000 steps/second. It depends on the software and
the speed
of the computer in those cases. The USC board moves that task into
hardware, and can
develop up to 300,000 steps a second.
