Having your own CNC (Computer Numerical Control) machine to do your own routing or cutting is very useful and fun, however some users find the to-and-fro between the computer and the CNC machine to be annoying. However this can be solved with the help of a Raspberry Pi which can be used as a WiFi transceiver for the CNC machine and thus allow remote control from another PC via WiFi.
This has been demonstrated by Instructables member eLVirus88 who shows how a CNC machine with a GRBL control board can be controlled over WiFi with not only a PC but with any web-enabled device on the local network. Doing so requires a Raspberry Pi to be dedicated to the CNC, and certain software such as GRBLweb to be installed however this is explained in detail.
If you're looking for a neat way to add external circuitry to your new Raspberry Pi model A+, B+ or 2 model B then check out our new PiBreak Plus Raspberry PiPrototyping Board:
This is a great way to add your own electronic components, circuitry, sensors or other devices to your Raspberry Pi model A+, B+ or 2 Model B - any of the current Raspberry Pis with a 40 pin GPIO header. The PiBreak Plus also includes a GPIO female header to solder yourself, and a pair of nuts, bolts, washers and spacers to ensure a a great fit.
And in the Freetronics fashion we've used a quality gold-plated (ENIG) PCB for durability, brought out all the power rails along with the GPIO next to the prototyping area to make adding circuits a breeze. Furthermore the pinouts are labelled on both the top and bottom of the PCB to save time referencing the right GPIO pins. For more information and to order - visit the PiBreak plus page now!
