Gcodes are created when you import an STL file into a slicing software. This leads us to our first question: How are GCodes created? Although gcodes are considered a fairly easy coding language, it is not recommended to write your own gcode: they are very complex, long, and if done incorrectly they can damage your printer. Gcodes are typically hundreds of pages long since they are directing every single action the printer is taking.
You can view the line by line code of the gcode by opening it in a text editor. Gcodes are actually used for a variety of machines, not just 3D printers ! Cutting tools likes lathes and mills also rely on Gcodes. These actions can include where the printer head goes, extruder temperature, bed temperature, pauses, printer head speed, and more.
Simply put, a gcode is a programming language that tells the printer what to do. We’ll review all the basics you need to know about gcodes: how they work, how to read a line of gcodes, and a gcode cheat sheet. Having a basic understanding of what gcodes are will help you in your 3D printing processes by allowing you to work more efficiently and possibly even more creatively. Gcodes instruct 3D printers on every action the printer must take, including movements, speed, temperatures, and much more. Files are free to download, but you can tip the designer if you like.Just as humans use language to interpret and understand actions and commands, 3D printers have their own language: Gcode demands.
If you choose to download a 3D model from Thingiverse you should find a model and then click the ‘Download all files’ button. Thingiverse as an example, from which you can freely download 3D models in STL format under a Creative Commons licence. There are dozens of sources online, and you may even choose to create your own in a separate 3D modelling app. Now you’re ready to bring in a 3D model to prepare for printing. Cura will remember these settings, so you won’t have to add them each time. Go to Settings, Printer, Manage Printers and, with your model selected, click Machine Settings. If you have to manually add a printer, you’ll also want to specify the dimensions of your printer bed. We selected Other, Creality CR-10, entered Ender 3 as the printer name and then clicked Add Printer. We’re using a Crealit圓D Ender 3, a great budget 3D printer that you can buy now from
