Many tutorials on this topic have become partially outdated, sparingly informal or a bit confusing; therefore, I have created an up-to-date tutorial for updating the firmware on a 3D printer using the latest versions of tools and software (as of this posting date).

!!UPDATE: Please note the "cool down" feature DOES exist, I didn't see it at the bottom of the menu at the time (sorry!), and didn't think to scroll down. Just know that it only pops up / reveals when the printer is in a "preheating" state. The "Cool Down" menu option will be in the same location as "Preheat PLA / Preheat ABS" but it won't show until after the printer is heating, and it will be at the very bottom of the menu.

Updating firmware on a printer shouldn't be stressful or cause you worry, so join me as I walk you through each step:

1- Find your printer's information: Board, Version numbers, Stepper motor driver model/make
2- Download Visual Studio Code (free) and it's extension: Auto Build Marlin
3- Download Marlin 2.1 firmware
4- Download the config files
optional: edit the code & add specialty functions
5- Compile / build the code
6- Copy file to SD card and insert into printer
