How Do I Update Cura/Firmware?

Periodically, you'll want to update Cura and your firmware. Cura is the slicer that Ultimaker supports. You can download updated versions of Cura here. When choosing which version to download, make sure you choose the most recent release for your operating system.

We recommend removing filament from your printer prior to installing a firmware update on your printer; also, it's helpful to do a factory reset after updating to make sure all aspects of the firmware update have taken effect. Never initiate a firmware update while in the middle of printing.

Firmware Update--Ultimaker 2 series and Ultimaker Original series

Downloading Cura on your computer does not change the firmware that is uploaded on your printer. For Ultimaker 2 series and Ultimaker Original series printers, use the most recent version of Cura to install the updated firmware on your printer.

  1. Turn your printer on and connect it to your computer via the USB cable that came in your accessory bag. 
  2. In your updated version of Cura, click SETTINGS on the top menu. Select the model of printer you are using, denoted by a checkmark. If you do not see the correct model, click ADD PRINTER and follow the instructions. 
  3. When the correct model is selected, click "Manage Printers."
  4. A dialog box will appear. Choose "Upgrade Firmware."
  5. The lights on your printer will turn off while the firmware updates. This is completely normal. 
  6. You can remove the USB cable once the firmware has been updated.

If you update your firmware and the printer no longer functions correctly, see our troubleshooting guide here.

Firmware Update--Ultimaker 3 series

Updating the firmware on your Ultimaker 3 or Ultimaker 3 Extended printer is not dependent on the version of Cura you're using. Ultimaker 3 series printers can be updated over the network from the printer itself, or via USB stick after downloading the most recent firmware.

  • If your printer is connected to the internet via wifi or LAN, you can update the firmware directly on the printer by going to System -> Maintenance -> Firmware Update.
  • Alternately, you can download the most recent firmware files from Ultimaker's website and save them to your USB stick and place it in the printer. Go to System -> Maintenance -> Firmware update and the downloaded file should show as visible and available to install from your USB stick.

    I believe a separate set of steps would be useful for windows based operating systems as the Cura 2.3.1 for windows does not have most of the menus mentioned in the steps above.

    Hi, Brian,

    Thanks for the feedback! I'm sorry we didn't see this note sooner. We're working on adding Windows images as well, to make the instructions more comprehensive.

    Could it be possible to update the firmware also on other Arduino based printers?

    Hi, Filiberto,

    You should be able to use Cura to update the firmware for other printers, but if the firmware file isn't in Cura, you'll probably want to choose the "Add custom firmware" option.
