Source code for updating Firmware

Recommended Posts

To update firmware, the easiest way is to take the latest version of Cura, which gets you the latest release build of the firmware and allows you to update it via a USB cable.

If you'd like to compile/verify the firmware yourself or make changes to the firmware, download the source code from here (assuming you use an Ultimaker 2): https://github.com/Ultimaker/Ultimaker2Marlin

It includes instructions on how to compile it (using Arduino's IDE) at the bottom of the page. You can make any changes you like to the entire source code.
