As the name suggests, it uses GRBL, a G-Code parser and CNC controller software package that was originally made to run on an 8-bit AVR microcontroller, but [Paul] designed the Super Gerbil to run ...

The built-in CPU’s software was severely outdated, had subpar algorithms for motor driving programmed in, and communication with the CNC ... wiring a grbl-fueled Arduino into the controller ...

grbl is stepper motor controller firmware for three-axis cnc machines, intended to run on Arduinos with ... But it was not much disappointment – I don’t want this to turn into a software project, and ...

The open-source grbl project has produced software that allows an Arduino to control a three-axis CNC machine – it is the software within ‘3018’ and related low-cost Chinese-made CNC desktop routers.
