However, some pronounce it “garble,” with others using a hard g as in “girl” in place of the soft g in “gerbil.” It probably doesn’t matter too much how you say it, as long as your machine is working hard for you.įor those who don’t know, a post processor (post) converts toolpaths from CAM software into g-code. Grbl continues to be a vital catalyst for desktop CNC hence, the noteworthiness of Sonny and Simen’s contribution.Īccording to Simen, Grbl is named after the animal, gerbil, because it is small and does one thing very well. Additionally, Grbl has forked into various other projects like TinyG, which is a conversation in and of itself. You can use it to automate all different types of machines, from hot wire foam cutters to 3D printers. Consequently, many companies utilize Grbl for their CNC machines, including Inventables, Carbide 3D, and Openbuilds. The software is open source and has a large community of developers and users. Grbl development began in 2009 under Simen Svale Skogsrud, and Sonny Jeon continued the work in 2011. Then the Arduino running Grbl software converts that g-code to motions on your machine. The g-code sender sends that g-code to the Arduino and acts as the human machine interface (HMI). To review, Fusion 360 generates the g-code from the model you want to cut. Fusion 360 generates the g-code, which you can then load into the g-code sender. The g-code sender also serves as the human machine interface (HMI) and runs on a laptop, computer, or Raspberry Pi. The Arduino receives these instructions line by line via USB from a g-code sender. G-code is the instructions that tell the machine what to do. It runs on an Arduino or similar development board. Grbl is software that converts g-code to motions on a CNC machine. What is it exactly? How is it pronounced? And most importantly, where do I find a Grbl post?
If you have spent much time with desktop CNC machines, you have probably run across the term Grbl.

In this post, we are going to explain how to get Fusion 360 running with a Grbl post processor.
