The proprietary control of CNC machines results in the inability to control and enhance inputs because the program codes cannot be modified owing to their distribution by vendors in the compiled form.

It's of course backwards compatible with existing Arduino add-ons, but sets itself apart with a new USB controller with lower latency and driver-free operation on Mac and Linux.

Chuck Todd has built a Arduino compatible Mega2560 expansion RAM that will enable those using the Arduino platform who need more that 8k RAM in the Arduino processor. Originally Todd created a ...

A cheap off-the-shelf USB to DB25 adapter may look like a good idea at first glance but they won’t work for a CNC application. [Bray’s] adapter is Arduino-based and runs GRBL.
