Can't update the Ultimaker 2 Go firmware

Product notification

This product has been discontinued and the end of service has passed. The information on this page remains available, but is no longer supported.

If Ultimaker Cura does not recognize your Ultimaker 2 Go when you want to upload firmware, there is a problem with the connection due to software or hardware failure.

Check the connections

The communication problem could simply be caused by a physical connection failure:

  • Make sure the Ultimaker 2 Go is connected to the power supply and turned on when uploading firmware
  • Check if the USB cable is properly connected and, if possible, try another cable to rule out a failure of the USB cable


Another possible reason for the connection failure is a bug in Ultimaker Cura or a problem with your computer or operating system (mainly with older versions).

  • Check if the latest version of Cura is installed on your computer
  • Try connecting on a different computer, preferably with a different operating system

If the options described above do not help to establish a connection, it is possible that the mainboard is defective. Contact support or your local reseller for a replacement.

Note: Because the Ultimaker 2 Go is a discontinued product, no new firmware versions will be released anymore via Ultimaker Cura. Also, the availability of spare parts is not guaranteed.
