DIY CNC Machinery
This post doesn’t have anything to do with making money online. However, if you’re interested in making money at home with some moderately expensive machinery, then I’ve got links to some pretty authoratative sites. Everything you need to build a 2, 3, or 4 access CNC machining center from scratch for minimal cost.
Building my own 2 axis CNC machine has been something I’ve been considering for a while, ever since I got the free dvd from PlasmaCam that I saw advertised in an issue of Popular Science a couple of years ago. The possibilities of what you can make with a CNC Router / Plasma Cutter are basically only limited to your imagination. I’ve been considering dipping my foot into the custom cabinetry field, but if I ever do so, nested based manufacturing will be go from day one.
I’m lucky in that I work in a factory, and can buy bulk metal from the company I work for, shear it to size, bend it any way I want on a brake press, and have the guys in tool and die machine some of the trickier parts. Not everyone has access to an entire manufacturing establishment. Even so, my major limitation is space, so when I build mine, it’ll probably be a fixed gantry/moving table design, rather than a gantry that moves on the X and Y axes.
For my first effort, I think it’ll be easier to build feed rollers to push the workpiece through, rather than dealing with building the railing and screws required for motion along the length as well as the width. Think of a giant printer, except instead of paper it’ll use 4′ x 8′ sheets of plywood, and instead of ink, it’ll use a router spinning at 20,000 RPM’s.
Majosoft is an amazing resource for CNC hobbyists. They have everything from plans for engraving machines up to full traveling gantry systems, and everything in between. Clamping devices, programming, software - this site has everything but the kitchen sink.
PM in MO focuses on portable, modular components for DIY CNC projects. They feature everything from PCB (printed circuit board) designs, stepper motors, and hardware drivers.
CNC Zone Forums are the ultimate hangout for CNC geeks. Ask, and ye shall receive an answer.
Engadget emarks on building their own CNC machines.
Massive list of CNC resources.
LinuxCNC.org home to free CNC software.
If the links above don’t get you started on the right path, I don’t know what will.
