![]() ![]() 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. įor better understanding, we can take a look at the following diagram:įrom the diagram we can see where the GRBL take place in the “big picture” of the working principle of a CNC machine. The GRBL uses G-code as input, and outputs motion control via the Arduino. We can easily install the GRBL firmware to an Arduino and so we instantly get a low cost, high performance CNC controller. GRBL is an open source software or firmware which enables motion control for CNC machines. So in this tutorial we will learn what is GRBL, how to install and how to use it for controlling your Arduino based CNC machine.Īlso, we will learn how to use the Universal G-code Sender, a popular open source GRBL controller software. ![]() If you are thinking or you are in the process of making your own CNC machine, then most likely you will meet with the term GRBL. ![]()
