Homebrew PCBs

OK . It just so happens I have been looking at these drives
www.xylotex.com looks great they also sell the steppers used at a good
price.
as far as software turbocnc seems to take it hands down it is dos it is
shareware it does work not crippled if you register for $20.00 you get the
source code.
they also have their own groups.
as far as slides I have built some from linear bearings and hard shafts.
there is one thing many people will be interested in this project.
how about you keep a log of you experiences and post them at the group or at
your site or???
maybe tell what you used as far as components/software/????? and why
this way others can learn from this
maybe put in their own .02 cents worth.
regards
victor
