Smoke,

I believe you misunderstood my explanation re: CncPRO.

The program "sets" a really low "top speed" through some internally
derived algorithm, which seems to have no REAL basis. In other words,
there appears to be some mistake(s) in the basic mathematical
assumptions used by the program. For slower (hobby machinist)
feedrates, it does not present a problem, but for faster speeds, it
can.

Sure, you could set up a 1:6 ratio and use a "fast" leadscrew, but
then the motors/drivers become unwieldy.

Hope this helps.
