Well, now we're cooking...

To list,

I'd just like to give an "attaboy" to Mariss, who suggested a
number of posts ago to someone that it's far better to run steppers
with as little reduction as possible owing to their speed/torque
characteristics.

This evening I took the 3:1 reduction off of the Z axis on my lathe
and put together a direct drive bracket for the stepper. The results
are amazing! Formerly, the max speed was 21 ipm. Now it's smoking
at 100 ipm (yes, on a 10" bed that's quite fast). Hmph. And I
thought I had it engineered right from the start.

Good stuff! I never imagined that there was such a gain to be had
in essentially all the same hardware...
