RE: [CAD_CAM_EDM_DRO] EMC step rate configuration

John -

Mariss at Geckodrive sells the G340, which is a G320 with a 10X
pulse multiplier. I ordered the G320's also, and he said that if
I ever needed the pulse multiplier, I would be able to order the
add-on board for a small fee, and install it within the original
box. It's supposed to allow a system with low step-rate output to
attain "microstep" precision. Check out the site:

I'm finishing up my grizzly/EMC conversion... How cool it feels
when
you
jog your first axis!

Now I'm thinking I've made a big design mistake: I used some
surplus
motors
with pretty high resolution encoders, which I'm driving with the
wonderful gecko G320's, and are coupled to 10 TPI acme screws
with 2:1 reductions. Working through the math, I end up with
MANY MANY (Way too many!) steps per inch. Way more than I
can use... (like 100000+ steps per inch)
