Joescnc looks pretty cool. The 4x4 CNC looks beyond the scope of an $800 project though given the amount of structural metal used. The older design had interesting elements - I like the torsion box base. Also just a note, I had the book on order and Amazon sent an email that it has been shipped, so the books are in. |

nox771: yes, a 4x4 workspace would double the workspace size of the machine I built but I'm betting the cost would be much more... increasing the width or length of the x axis has an immediate effect on the y axis - many of the y-axis parts will now double in size, as will your hardware costs (more bolts to keep the rigidity constant). Thanks for buying the book! I really hope you'll post a picture (or pictures) as you build and I can't wait to see what you do with it! Jim |

If any of you are interested, we have most of the full color photos and videos on the book's website now - http://buildyourcnc.com/Book.aspx - just click on a chapter along the left side of the screen. We're not 100% done yet, but we're almost done... we have a LOT of videos to upload and are only up to chapter 13 at this point... 6 more to go. Jim |

So I've got myself the book and I'm thinking about giving this a go but I can't locate the bill of materials... Am I missing something? Shouldn't there be a list of how many nuts and bolts and in what size are required? I know there's a "Hardware Required" section at the end of each chapter but being a purchasing agent in a custom manufacturing facility for a couple years has shown me just how important a B.O.M. is... I suppose I could go through the book and add everything up but even if I did that I wouldn't have stuff like the length of the lead screws which as an example, in figure 9-9 of chapter 9 it says "Mark an extra 1" of lead screw on both ends of the table and cut." While I can imagine that since the book is aimed at those who might not have the skills (as accurately as you would like) to cut the whole thing out, assemble it and expect everything to line up perfectly, it is frustrating from a perspective of a mechanically inclined person who just wants to order all the hardware in one go. Here's hoping that you've got a B.O.M. for me and a suggestion to put it up on the website and maybe consider putting it in version 2 of the book if that's any sort of possible. |
