After browsing many websites in search of CNC machines and their construction it soon became apparent that every machine I saw had been constructed quite differently. My conclusion to this, is that we all build within our range of skills and use the materials that we already have to hand or which are readily obtainable. My CNC machine falls into this category exactly - It is probably the best I can achieve within my abilities and with the materials I can obtain. For my construction, I chose to make a welded steel frame using fully supported linear rails and ball screws for the X and Y axis with round linear rails and a trapezoid lead screw being used for the Z axis, all direct driven with bi-polar stepper motors. My exploits into the world of CNC have been and still are great fun and as a hobby it can be extremely rewarding, I recommend it to anyone seeking a challenge.

DiY. Homemade Router Laser CNC. In this page I will show you how I have build a Router Laser CNC using some part from old printers, a Epson Stylus 800 and another Epson Stylus Color II, (you can use your old printer). Aplications: Cutting Paper. To make stencils for painting with airbrush.Wood and Cardboard Engraving. Write and paint in wood whitout ink.Plastic Engraving. To write in plastic without special inks.Plastic Cutting. DIY CNC Router – Initial Designs Intial Design with shallow table Had to take a break to raise some funds. In the meantime, I went ahead and modeled as much of the machine I want to build in Sketchup. Granted, Sketchup is probably not the best modeling tool, but I find it the fastest for whipping out designs and dimensions. You’ll notice that I color coded the pieces as best I could. The blue parts are rectangular steel tubing, the gray is cold rolled 1/4″ steel plate and anything white should be aluminum.

MadVac CNC - home made 4'x8' cnc precision gantry router The design objectives for MadVac CNC: General purpose 4 axis (two Z axis) production machine capable of 2D and 3D routing of material within 7" x 52" x 99" envelope Milling wood, plywood, plastics, all grades of aluminum and softer metals 3D mold making Repeatability and precision of movement to 0.0005" and better Heavy, relatively rigid structure Easily accessible open table Small footprint base Modular design for disassembly, moving and reassembly Repeatable and accurate assembly Upgradeable to servo motors Compact Y gantry with Z and W axis both of which can work in 52" x 99" envelope Mobile controller console that can move to any point around the machine Complete mechanical, electronics, software system under $16,000. A few random thoughts and reflections about the project: The research, design and planning of every component, materials and aspect of this machine took about one full year and the construction itself started in Jan 2004 and was 95% finished in July 2004.

DIY CNC Third machine was Jabott and this was just a fun little project using up bits and pieces I had accumulated. Fourth Machine was Rodot and I took a lot of time modifying my design to improve the machine. Note the cranked gantry. Here is a hybrid X2 mill I did. It has a larger table and very much modified column. Homebuilt CNC Router #1: A Journey - by SPalm After posting my Woodworker’s CNC Router in the projects section, I received several requests to show how I made it. I debated whether to post something here or just send them off via a bunch of links. I decided to show you the journey that I took over several years and ended up with the machine that was posted. So here goes. 25x25~Solsylva CNC Plans Construction These plans are for builders who have a minimum of tools and only modest shop experience. The plans include detailed step by step directions with dimensioned drawings of all parts. This machine is made of stock sized boards (1x4, 2x4, etc.) that are cut to length and drilled.

Aaron Bowser’s CNC Machine Thinking about building a CNC machine? Hacked Gadgets forum member, Aaron Bowser has a site loaded with information on how to build one. Not only is there helpful information about his design, there is also a vast number of links to other resources. “The mechanical design of the machine was based on a survey of CNC machine websites and on the availability of used and surplus parts. A y-axis gantry style, similar to the one used by Axxus Technologies, was selected. The stepper driver board currently used in this project was created based on the application notes from the UN5804B stepper driver from Allegro Microsystems.

Black Rynius' Blog CNC Machine Front view. Machine Type DIY Desktop CNC Machine by Stephen A modular, inexpensive, versatile desktop-scale CNC machine to put computer-automated machining and fabrication in the hands of creators. Whether they be hobbyists or evil scientists, small-scale manufacturers or budding inventors, the power to go from on-screen design to precision-machined product in a few mouse clicks is very exciting. See this project Updates section for pictures and video of the working prototype. smartCaster: Open source automatic roto-casting machine by Aurelio Reis A rotocaster has a few advantages as well as a few disadvantages to a 3D printer, meaning it does work very well as a compliment as opposed to replacement. Materials wise you have a big advantage as you can use a casting material with different texture, strength or flexibility whereas with 3D printers it's usually some sort of rigid plastic. Casting materials tend to be a little on the expensive side unless you buy in bulk so I would say it's about a draw there with the 3D printer maybe being a little cheaper. While the option does not exist with rotocasting some of the more expensive 3D printers allow you to print with different colored plastics to make non-solid colored objects but this is not common. Finished (roto)casts are high quality and usually don't need much post processing to be usable whereas most (affordable) 3D printers do require some degree of finishing since they tend to create objects with strange surface properties.
