Re: Servos and Controller boards

Tom,

I think many would (and do) say the same thing about building a cnc
machine...

(Why build when I can buy a perfectly good one for a great price?)

I hope your reply doesn't keep folks from trying. After all, if
everybody only did what was "economical", we'd still be buying
expensive CNC machines.

We are the recipients of MANY folks who "work for free", and I hope
that each one of them continues to find learning and sharing a
worthwhile exercise, so that one day we can have as many servo
options as we now have for steppers...

P.S. As "list mom" of the DIY-CNC group, I've heard a few "reasons"
given in answer to the recent thread about posts at CCED. And they're
NOT all about moderation... Many have told me that they are
frustrated by: asking a question for technical advice, only to get a
reply for a commercial product to buy. We're trying to build NEW
options, NOT just continue with the old ones... (And "money" is NOT
the only motivation.)
