CNC Diagram I don't remember exactly where it is. But somewhere you have a fully functional diagram demonstrating electrical flow through diodes, capacitors, AC versus DC, etc. It's absolutely wonderful, helped me a lot. I wish you would expand on that and put up a diagram showing the workings of a typical hobbyist CNC router. I have made a rough stab at it (see link above), but some of the info is missing. Why? Because I'm a newby and don't know where those wires go or what's in that box. Such a diagram would help me a lot in knowing what to buy next and where it goes. After a while you could describe typical values for the components. For example you could note next to the stepper "a popular size for this kind of application is the___ and costs about ___." I'd love to be a part of such a project. A committee organized for the purpose of helping the ignorant should include one ignoramus. I'm your man.
