Arduino CNC Shield – For connecting the stepper drivers to the Arduino, the easiest way is to use an Arduino CNC Shield.Drivers – For driving the stepper motors we need drivers and common choices when it comes to smaller DIY CNC machines (using NEMA 14 or 17 steppers) are the A4988 or DRV8825 drivers.Stepper motors – Obviously, the stepper motors provide the motion of the machine.Specifically, we need an Atmega 328 based Arduino board, meaning that we can use either Arduino UNO or Nano.

Arduino – As we already said, we need an Arduino to install the GRBL.In other words, the function of the GRBL firmware is to translate the G-code into motor movement.
It’s a firmware that we need to install or upload to the Arduino so it can control the stepper motors of the CNC machine. Stamp_type.From the diagram we can see where the GRBL take place in the “big picture” of the working principle of a CNC machine.
