Download GRBL Library
GRBL Library files help microcontroller to understand the co-ordinates numbers which we have provided as “.gcode” to GRBL controller software and according to the “.gcode” file current and voltage provided by the controller to CNC shield and there are stepper motor drivers on the CNC shield for each stepper motor, which amplifies the microcontroller’s voltage and provide to the stepper motors.
So before launching the GRBL software you must include these GRBL library files to compile grbl programs and upload it to Arduino.
Note: If you don’t know where to place this library on a computer and how to configure everything please watch our video till the end. Here is the video:
