Ready for some hard core gadget creation If you thought your dremel tool was handy before, in today’s How-To we’ll start building our own CNC machine. Aside from the geek factor, it can be handy for making things like PC boards without chemicals or maybe some little styrofoam voodoo heads of all your friends.
Computer controlled mills have been around for a long time. If you just want to buy oneone, Sherline makes mills that are ready to go (pictured is their CNC ready model — just add your own motors and controller). But then again, if you wanted to buy one, you probably wouldn’t be reading this, now would you A CNC machine is a lot like a precision drill press with a table that moves in two directions — seeing a commercial unit like the one above should help you visualize the end goal. We’ll be making ours from scrounged, recycled, and adapted parts; today we’ll be going over the basic parts we’ll need to build our own.
Gentlemen, start your soldering irons.
