Hi,can anyone suggest a suitable beginners guide to cnc, which explains the most basic components and their applications. As far as electronics are concerned, i can put a battery in a torch, change a fuse, and that is about it.When i read your various build details, the mechanical parts are not a problem, but as a complete novice when it comes to electronics components and their function i would dearly like to learn from absolute basics onwards.So if anyone can help it would be much appreciated.
