Marlin

Marlin is an open-source firmware that controls 3D printers, CNC machines, and other types of machines that use G-code to operate. Simply put, it is the firmware that acts as a translator between the machine and the user, who provides commands via G-code related to the behavior of the machine.

It is important to note that you can’t use the tool directly from your Windows computer, and you will need to rely on a third-party host software for this purpose. The developer provides a few suggestions on the Home page, so don’t hesitate to take a look. If you decide to work with a host software, then make sure you create the USB connection between the printer and the PC.

The firmware provides an alternative way of printing via an SD card in a standalone mode. What this means is that you save the G-code files onto an SD card so that the printer can read and execute the commands directly. It goes without saying that you need to create and save the G-code files beforehand.

The firmware comes with full-featured G-code supports, meaning that it can interpret over 150 commands and hence, you can gain better control over your printer. It supports the G-code movement suite, which are essentially commands are used to control the motion of the printer's extruder and print bed during printing.

It is also worth mentioning that the tool comes with a smart motion system that enables it to predict your machine’s behavior and adjust it accordingly. The results are likely to turn out more accurate.

Marlin is a handy firmware suitable for anyone who regularly uses 3D printers for various projects. Not only does it help you get more control over the printer, but it also provides a more convenient way to manage all real-time activities of the machine.
