In order to install the latest firmware to your Ultimaker 2 (Extended), follow the steps described below.

Use the supplied USB cable to connect your Ultimaker 2 to a computer or laptop that has Ultimaker Cura installed. This will allow Cura to communicate with the printer.

Install firmware

Tip: Ensure that the correct machine (Ultimaker 2 or Ultimaker 2 Extended) is selected in the Printers panel.

Note: If you have installed the Extrusion Upgrade Kit, your machine is now an Ultimaker 2+. Ensure to select the Ultimaker 2+ in Cura when installing new firmware, otherwise, your feeder will turn the wrong way.

In the Printers panel, select Manage printers. From this menu, you can update the firmware. This menu offers two options:

Automatically upgrade firmware Selecting this option will install the latest version of the default Ultimaker firmware for the Ultimaker 2 or Ultimaker 2 Extended.
Upload custom firmware It is possible to install custom firmware for your Ultimaker 2 that you compiled yourself or found online. Installing custom firmware is always at your own risk.

Wait for the firmware installation to complete. Do not disconnect the USB cable or power off the printer during the installation process.

Note: The firmware for the Ultimaker 2 has not changed for a long time. While we still recommend always using the latest version of Ultimaker Cura for the best print results, new Cura versions no longer contain any updates to the firmware for the Ultimaker 2.
