Superb Wood Floor Inlay Shows Off Computer-Augmented Tools

It’s been a few years since we first started hearing about “tools of the future changing the way we work” but this astounding whole-room floor inlay might be the best argument for them yet.

The Shaper Origin

A couple of years ago we wrote a hands-on preview of a unique tool called the Shaper Origin. If a milling machine is classically defined as having a stationary tool head with moving stock, the Origin is the reverse. To use an Origin the user adheres specially marked tape to the stock material, then holds the origin down and moves it much like a hand router.

The Origin has a camera which tracks the fiducial patterns on the tape, allowing it to know its precise position, even across an entire room. The operator sees a picture on the screen of the tool that guides them with superimposed lines, while the tool head makes its own precision adjustments to perfectly cut the design in the X, Y, and Z.

Floor in Progress

But what do you use a tool like this for? Cutting boards, small tables, and toy blocks are fine examples but don’t highlight any unique features of the tool. Many could just as easily be made using a ShopBot, X-Carve, Carvey, or any of their ilk. What you can’t do with any of those tools (or really anything besides manual labor, endless patience, and master skill) is inlay an entire floor in situ.

[Mark Scheller] (eight time winner of Wood Floor of the Year awards) used an Origin to cut a curvaceous 22 foot long rendition of the first 9 bars of Handel’s Passacaglia into the floor of a lucky homeowner’s music room. Without decades of practice, it’s difficult to imagine doing this any way besides with a Shaper Origin. You can’t put an entire room into a CNC router. The individual floorboards could be cut, but that would be tedious and increasingly difficult as the room gets larger. With the Origin it seems almost trivial. Do the design, place the marking tape, and cut. The same model is used to cut the inlays for a perfect fit. This is an incredible example of a unique use for this unusual tool!

DIY MDF CNC Machine Is Small And Solid

In the world of hobby-level CNC cost and simplicity are usually the name of the game. Using inexpensive and easily found materials makes a big difference in the feasibility of a project. [FreeRider] had built a CNC router before but it was big, flexible and not as accurate as he wanted. He set off to design his own table top router, influenced from other designs found on the ‘net, but also keeping the costs down and ease of build up.

The machine frame is made from 3/4″ MDF and was cut on [FreeRider’s] first router, the JGRO. Notice how all the holes are counterbored for the many bolt heads. It is clear that much attention to detail went into the design of this machine. Aluminum angle act as linear rails on which v-wheel bearings travel. Skate bearings support 5/16″ threaded rod used as lead screws. Lead nuts are tapped HDPE blocks and seem to be doing a satisfactory job with minimal backlash.

[FreeRider] says his new machine is capable of 60 inches per minute travel, double that of his old machine. Since the new machine is stiffer, he’s able to route aluminum and has successfully made some brackets out of 1/8″ plate. He reports the dimensional accurate to be about 0.002-0.003 inches. For more inexpensive MDF-based CNC machines, check out this drawer slide bearing one or this one that uses a drill for a spindle.

Resourceful CNC Router Built From Hardware Store Parts

[siemen] has entered the wonderful world of Hobby CNC with his low-buck build of this gantry-style router. It embodies everything we here at HaD love: resourcefulness, perseverance and results. [siemen] has designed his frame using ideas he has found while surfing around the ‘net and is made entirely out of particle board. For linear movement, the Y and Z axes rely on ball bearing drawer slides while the X axis use a pipe and skate bearing arrangement. NEMA 17 stepper motors coupled to threaded rod move each axis.

The electronics are packaged in a nice little project box which houses an Arduino and 3 Sparkfun EasyStepper stepper motor drivers. [siemen] also cut a hole in the project box and installed a fan in order to keep those motor drivers cool. The Arduino is flashed with the CNC machine controller called GRBL. GRBL takes g-code sent from a PC to the Arduino and then in turn sends the required step and direction signals to the stepper motor drivers.

Overall, [siemen] did a great job with his first CNC project which came in at 200 Euro ($240). He’s currently working on version 2 and we are looking forward to covering it when it’s done. If you dig this project, you may also like this wooden wood router or this bolt-together one.

Building a Wood CNC Router From Scratch

home made cnc router

[David Taylor] needed a CNC router to do some more complex projects — so he did what any maker would do if they’re strapped for cash — make it from scratch!

The impressive part of this build is that it was built entirely in his workshop, using tools he already had. A chop saw, wood lathe, drill and a drill press, and finally a table saw — nothing fancy, but now with the CNC router he has a world of possibilities for projects! The mechanical parts he had to buy cost around $600, which isn’t too bad considering the size of the router. He lucked out though and managed to get the Y-axis and Z-axis track and carriages as free samples — hooray for company handouts!

The router is using an old computer loaded with LinuxCNC which is a great (and free!) software for use with CNC machines. It’s driving a cheap Chinese TB6560 motor controller which does the trick, though [David] wishes he went for something a bit better.

Some examples of the projects he’s already made using this baby include an awesome guitar amp, a wooden Mini-ATX computer case, and even a rather sleek wooden stereo with amp!

Did we mention it can even cut non-ferrous materials?
