G-Code Reference Block Library

INTRODUCTION

Are you passionate about CNC machines, 3D printing, or laser cutting? Meet GRBL – the open-source software that’s transforming the way we interact with these advanced technologies.

What is GRBL?

GRBL is a free, open-source software that runs on microcontroller boards like Arduino. It allows seamless transfer of G-code from a USB-equipped computer to the stepper motor controllers of CNC machines. Traditionally, these machines relied on the outdated parallel port (LPT) of computers, which is now almost extinct in modern hardware. GRBL bridges this gap, making high-tech CNC machines accessible and affordable for fab labs and hobbyists.

Why Choose GRBL?

Affordable and Accessible: GRBL brings the capabilities of expensive CNC machines within reach for individuals and small labs, democratizing access to advanced manufacturing technologies.

Academic Applications: Used in university research, GRBL supports various machines, from milling machines to robots used in biological studies. For instance, it has been employed in studies involving Drosophila melanogaster, a type of fruit fly.

Optimized Performance: GRBL’s G-code parser, written in C, is highly optimized for the ATMEGA328 microcontroller found in Arduino boards. This ensures efficient and precise control of your CNC machine.

Extended Capabilities: The original GRBL supports 8-bit microcontrollers. However, ports to 32-bit microcontrollers like STMicroelectronics STM32 have expanded its capabilities, allowing for faster and more powerful machine operations.

How Does GRBL Work?

GRBL converts G-code – the language used to control CNC machines – into signals that drive the machine’s stepper motors. By running on an Arduino, GRBL provides a cost-effective and versatile solution for DIY CNC projects. Whether you are building a 3D printer, a laser cutter, or a milling machine, GRBL can handle it all.
