I'm not comfortable running my Sherline at 30ipm in the first place! I
have rapid speed st at 20ipm. My Z axis is also balanced (spindle motor
behind the column) and spring-counterbalanced so it should be about optimum
for the nut life. Moglice recommends Vactra #2 way oil (at least, that is
what their booklet calls out in the wear charts) so that is what I'll be
using on my leadscrews.

The Sherline steppers were able to run the axes at 20ipm as soon as I
hooked them up. The Y axis did skip once on the first rapid only, then no
axes skipped at all when I jogged them all from end to end about 6 times
(at the 20ipm)

For tauseef, I must admit that I never measured the backlash with an
indicator before the conversion, but from the size of some parts I made
under CNC (vs. the programmed dimensions) I estimate it was .005" at least
in X and Y.

Best regards,
