Steppers versus Servos

Okay,

It sounds like people are getting tired of this. I am sorry if I have caused
such trouble.

Well, I have lost some "bookmark" files, and will not do a new search on
stepper systems, - but :

My inputs have been more of a "DIY" - and ideas. In any commercial
system, a lot of engineering has been conducted. And as Ron said:
" If the motor is run within its design limits, it does NOT loose steps.
PERIOD. "

I will not argue, but a lot of these commercial systems, have some real
fancy drives. If you buy the "right" stuff, do good engineering, - then most
of what I have said - is a waste of time and effort.

But some of the "stuff" I brought up, might once in a while open up some new
tips & tricks. And sometimes you have to state "stupid" questions. In fact
refrasing a question, - is often the key to any new development.

I will rest the "stepper" case for now.
