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.
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.
