Re: Looking for as much info as possible to construct a CNC system

Hi,

Welcome to the list.

I would recomend you read the Gecko white paper on power supplies at
www.geckodrives.com that will offer most of what you need to know
about power supplies.

search this list for words like power and torque, you'll get hundreds
of hits, but there are threads that talk about how to select the
motors and gearing for any drive. basically determine required
torque and all the calculations needed to select motors.

then of course, read all you can about lead screws and ball screws.
you will want to know what is best, and the differences.

check all the posts in the files section and photos sections and the
links in the links section. don't forget the home page for the list
and Tim's page with more links.

I knida wish one of us would have put together a list of post #s in
the files section for just what you are asking.

Dave
