The page is a remarkably thorough guide to setting up a CNC robot workshop at home, and a first article in a series on CNC robotics. I created it simply because there are virtually no books or useful reference pages for people who want to get into @home fabrication without an extensive background in machining and materials science.

The page itself is devoid of images (although there are some rad ASCII illustrations), so to see some of Michal’s work, visit his photo page.

    Guerilla guide to CNC machining…. Very crude! Absolutly rough in spots. Would have liked to have seen more of a guide to what works best as appossed to what didn’t work in general. What is the software of the user that produced the parts on the picture package, as these look great! And in this what was the total cost of the package that included the machine, TYPE, and Software used to product the geometetries of those images. A guide to random bits of precision didn’t help at all as the software CAD/CAM and machine must work in concert to produce these parts. The person probably can say for sure what will work for everyone, but to know the cost of the system and the software and type of each in its class would be helpful. Was this a $1000.00 machine with a $200.00 peice of software or was this an $8000.00 machine with a $3000.00 peice of software? All of that could and would make a big difference.

      you complain when the bubblegum machines dont give you the right color of gum dont you? JC man, lighten up. He didn’t say this was a college credit course.

      M.K. put a lot of info together. If you read the post you would have learned that the work was likely done with the Roland machine he mentions early on. He details that his area of interest is micro machining. Clearly he isn’t using a woodworking router based machine, although he lists manufacturers that offer such machines. His information is far from crude, it is an overview. The field is so broad and varied, M.K. could have written for days and not covered it all. He does provide many useful threads to follow for those that are not intimidated by some research.

    crude but it gets the job done, good for hobbyists and beginner diy enthusiasts, my blog is better
