since we're on this subject...

If I have very high resolution encoders, say 50000 cnts/inch, can I use the
step pulse multiplier feature in the Gecko G340 to reduce the effective
incoming pulse count? Is this what that feature was designed for? I just
liberated some 2500 line Koyo encoders from a milling center and I'd like
to use them for a step/direction servo setup on my lathe. It'd save me
having to shell out an additional $80 each for new 1000 or 500 line
industrial grade encoders.
