Steppers lose steps.

Servos baby 

:-)

And forget both …

Have scales for feed back, don’t use the ball screw driver for position. That and code that has predictive motion . Now I’m into area I have no knowledge…. G code has predictive but the industry is so more advanced than I can understand . 

That said, I’m using servos and steppers in the machines I use. Can’t afford the really  good things… like a kern cnc :-)

Boolean Algebra.  Things sure happened marvelously from then on.  And there was this marvelous electronic machine, used a language called "Basic".  Soon after, more languages...like "Fortran".  Oh my!!  And about 10 years later, some geeks put together something called a "Personal Computer".  I couldn't imagine why anyone besides an engineer would want one.  I was wrong.
