Definition
What Are GRBL Controllers?

GRBL is an open-source software or firmware which enables motion control for CNC machines. we will easily install the GRBL firmware to an Arduino then we instantly get a coffee cost, high-performance CNC controller. The GRBL uses G-code as input and outputs motion control via the Arduino.
Harware Requirement For CNC GRBL Controller
Arduino –
As we already said, we’d like an Arduino to put in the GRBL. Specifically, we’d like an Atmega 328 based Arduino board, meaning that we will use either Arduino UNO or Nano.
Stepper motors –
Obviously, the stepper motors provide the motion of the machine.
Drivers –
For driving the stepper motors we’d like drivers and customary choices when it involves smaller DIY CNC machines (using NEMA 14 or 17 steppers) are the A4988 or DRV8825 drivers.
Arduino CNC Shield –
For connecting the stepper drivers to the Arduino, the simplest way is to use an Arduino CNC Shield. It utilizes all Arduino pins and provides a simple thanks to connect everything, the stepper motors, the spindle/ laser, the limit switches, cooling fan, etc.
