22 October 2019

Firmware 5.3.4 primarily addresses the cloud connection workflow on the Ultimaker S3.

  • Cloud Connectivity. Some users were reporting issues when establishing a cloud connection to their Ultimaker S3. This is now resolved and the Ultimaker S3 can fully benefit from Ultimaker Cloud functionality.

Known issues

  • Retracted filament after Welcome setup. After performing the Welcome setup on the Ultimaker S3, the filament is retracted from the nozzle. When starting a print following this, the print job begins with filament retracted too far, affecting the first layer.
  • Freezing during Wi-Fi setup. In some exceptional cases, the Ultimaker S3 display may freeze when attempting to connect to Wi-Fi. Restart the machine and try reconnecting to resolve this.
