If Ultimaker Cura does not recognize your Ultimaker Original+ 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 Original+ 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 Original+ is a discontinued product, no new firmware versions will be released anymore via Ultimaker Cura.
