We’ve seen some impressive custom-built CNC controllers over the years, but between the mostly off-the-shelf hardware used and impressive UI, we think [Steve] has created something unique.

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 ...

Personal computers with CNC software do not require specialized hardware such as programmable logic controllers (PLCs) or motion control cards. The CNC software performs all of the functions of a ...
