CNC Robotics: Build Your Own Workshop Bot 1st Edition

Great info and great place to start. Great reading. Diagrams are good and easy to follow. Good book to have

Interesting book, I think I'll build one

good reading a little outdated

the Motorola V9 razors are not set up right. When you try and text, the whole bunch of characters come up other than the ones you punch and you cannot receive a photo like phones I purchased direct from ATT. A little disappointed. Maybe I can get a ATT rep to help formulate the phone. I do like yhe Nokia phone. It is great. I bought a few of them and went back to order 3 more and found out that the outfit had raised the price overnight from $75.00 to $248.00. I would like Amazon to tell those guys to knock that BS off.Amazon does have a good system in place and I like the pay system unlike "GooglePay" which one time they took the $500.00 but didn't pay the guy I bought the phone from so I never got the phone and there is no physical way to e-mail or call Google.. Googlepay "sucks".Like I saud, it appears that Amazon has a very good system in place and as a matter of fact a gal did call me to make sure it was me ordering all those phones. I have about 10 lines at ARR and run ffish boats.Ray Forsman 360 202 2201

A little heavy on electronics

At best, it is just "build a machine that response to CNC program (G-Code)to kill your time - if you have too much."Ask yourself the follow question before buy this book: Can you accept a CNC with unknown accuracy (my guess is 1mm error at best)? If you can accept it, this book is for you.I didn't and will not follow the author's path, followings are the reason:1) He use scrap material, he dismantle his camera for "liner rail", he find "square" beam from scrap shops...etc. His measurement of "square" is based on combination square. His measurement of level is based on "trial & error" with height gauge, not even dial indicator.2) He use stepper motor based on "available" and didn't mention how you can estimate the required torque to drive the ...... ACME lead screw. ACME is good for its lower cost compare with Ball screw, but you've a price to pay, backlash. Some CNC software can handle it, but the author just didn't care. I doubt when it mill a square, will / can it closes the path?3) It is just a CNC table that clamps a pen or a router on its Z-Axis. So, it is just a wood-working CNC router, not a CNC machine, definitely not `robotics' standard. God, the book's name is too sexy for me.4) Don't expect any calculation / estimation that can help to design you own CNC, there is no such thing in this book, and everything is done by wild guess.5) Don't expect to gain any insight from watching / learning the author's approach to build a CNC. He use lengthy text description on how he drill a hole, put the steel beam in level (concrete floor) and use "measuring tape" to locate the centers for drilling. It is terrible, if you're a (hobby) machinist or dealing with metalworking. Can you imagine to 'arc weld' your machine's frame? What accuracy will leave for your measurement after such a destructive task is done?Why I buy this book? It's because the author write a very sexy preface and introduction, a very logical table of content, and most important, Kindle let me preview only up to the first chapter. My verdict: save your money.If you can settle with the low accuracy & repeatability, why need a CNC? If you just want to repeat routing a 2.5D pattern, just make yourself a fixture / jig / template will be more than enough.

Thanks a lot for your kindness and goods

CNC Robotics gives simple step by step directions for designing a CNC robot and how to do it on a budget. Worth what I paid for the book 10 times over.
