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?
