Query: This book is better on making PC Boards than on CNC...

I, too, couldn't wait to get my hands on this book-- only to be very dissappointed when I got it.Nearly 100 pages (a third of the book) are spent describing how he made his own circuit boards, assembled them ,etc. It seems really silly when better micro-stepping controllers are available for around $100.There is almost no discussion of design theories. He just found this great surplus sliding unit from a $3000 graphic arts copy camera and decided to build the rest of his machine around it. Good luck to you trying to find one just like it!There is much better information available on the web and in the newsgroups. Save your $35.
