With the first G00 command, we quickly bring the machine from its home or initial position to the point B(5,5). G01 X -26 Y -2 point B Code language: Arduino ( arduino ) This results in a straight line movement to the new position point. ![]() The machine will move all axis at the same time so they complete the travel simultaneously. The G00 command moves the machine at maximum travel speed from a current position to a specified point or the coordinates specified by the command. We will learn how each of them work through several examples, and by the end of this tutorial we will be able to fully understand how G-code works, how to read, how to modify and even how to write our own G-code. So, now as we know how to read a line of G-code, we can take a look at the most important or commonly used G-code commands. The most Important/ Common G-code Commands If we want the units in inches, we use the G20 command instead. The unit is mm/min because if we take a look back at the G-code example image, we can see that we have used the command G21 which sets the units to millimiters. Lastly, with the F value we set the feed rate, or the speed at which the move will be executed.We declare the position or the coordinates with the X, Y and Z values.First is the G-code commandand in this case that’s the G01 which means “move in straight line to a specific position”.Let’s take a look at a single line and explain how it works. It seems that the “complicated” part of the G-code are all those numbers we see, which are just Cartesian coordinates. If we take a closer look at the code, we can notice that most of the lines have the same structure. How to read G-code Commands?Īt first glance, when you see a G-code file, it might look a quite complicated but it is actually not that hard to be understood. Similarly, in case of additive manufacturing or 3D printers, the G-code commands instruct the machine to deposit material, layer upon layer, forming a precise geometric shape. In case of a machine tool such as lathe or mill, the cutting tool is driven by these commands to follow a specific toolpath, cutting away material in order to get the desired shape. ![]() ![]() The G-code commands instruct the machine where to move, how fast to move and what path to follow. We use this language to tell a machine what to do or how to do something. G-code is a programming language for CNC (Computer Numerical Control) machines. So, in this tutorial we will learn the basics of the G-code language, what are the most important or common G-code commands and we will explain how they work. If your work or hobby correlates with CNC machines or 3D printers, then understanding what G-code is and how it works is essential for you.
