Engineer's Edge Gunnebo Johnson Corporation ASTM Standards Originally called the American Society for Testing and Materials, ASTM publishes a wide range of standards, focused on materials, but also covering products, systems and services. If you are doing business in the USA, ASTM standards can make compliance easier. ASTM standards have been adopted, by incorporation or by reference, in many federal, state, and municipal government regulations. You can now find and purchase over 12,000 ASTM standards through the BSI Shop. To find them, you can search on the standard number, i.e. ASTM standards are available in hard copy and for PDF download. ASTM standards cover: Search the BSI Shop for ASTM standards.

3 Axis Arduino Based CNC Controller I've been playing with different CNC designs and Stepper controllers for many years now. I started building CNC machines long ago. My first inspiration came from Bruce Shapiro’s eggbot. I tried a few variations of it and even the board from evil mad scientist. The latest generation controllers I have built all use the same simple and cheap IC's. I've used the cheapest parts I could find and still got great results with modest fine tuning.
