Geoff Williams CNC Bot book was Re: More questions

Hello, I just lost a long reply to this. Without re-typing it I'll
just summarise. I purchased a copy of this book. IMO the book sucks...

A lot of info on the L297-L298 and making not even very good drivers
using them (With about 50 pages of the chip data sheets which can be
gotten for free from www.stmicro.com) The bulk of the book is on
building these drivers.

The surplus parts he uses are from a process camera, and not the kind
of thing you'll find easily. And he spends too much time telling you
how HE did it, and not enough IMO teling you how YOU can do it.

The machine design itself will probably work, but I don't think it's
a very good design. I think your parts will be filled with chatter
marks...

Go to www.cnczone.com to see the depth and breadth of first-timer cnc.
IMO, you'll get FAR more out of spending the same time there that you
would have spent readin the workshop Bot book.

I'd recommend against buying this book.
