Firmware 5.2.16

October 29, 2020

The Ultimaker Cloud and Connect services were rebranded to Ultimaker Digital Factory in June 2020. This firmware update will enable Ultimaker 3 firmware integration with the Digital Factory.

Digital Factory integration. Print jobs sent via cloud show print job preview images in the Digital Factory. Printer discovery including connection, cancelling, and removal have been made more robust

Digital Factory functionality. The Ultimaker 3 will be able to start, stop, pause, and resume print jobs remotely

Updated UI elements. Some UI elements have been updated to more closely match the new Ultimaker branding, and the "add printer to group" UI was simplified

Firmware 5.2.11

May 14, 2019 

Firmware 5.2.11 is a hotfix release to correct issues reported in firmware 5.2.8. This hotfix will address the issues discussed below:

Update via USB. Fixed an issue where printers without a network connection couldn’t update to the .swu file system. Users that tried to upgrade to firmware 5.2.8 via USB would get stuck on the stepping stone version due to a mismatch between the onboard time stamp of the printer, which would default to standard Linux (UNIX) time, and the timestamp of the downloaded file.

XY calibration. Fixed an issue which prevented the XY calibration procedure from extruding properly. All printers running firmware 5.2.8 would initiate the XY calibration procedure with filament in a retracted state. This meant that the procedure would finish its sequence without extruding correctly. Firmware 5.2.11 ensures that filament is fully primed before initiating XY calibration.

Screen issues. Fixed an issue where the screen on the Ultimaker 3 shifted or rotated. Firmware 5.2.11 included a redundant feature that was interacting with the Linux kernel in an unexpected way, leading to shifted or rotating screens. This feature has been completely removed in firmware 5.2.11.

Third-party materials. Abrasive materials have been removed from the Ultimaker 3 material selection menu, as printing abrasive materials will damage the Ultimaker 3 feeder wheel.

Known issues

Wi-Fi on the Ultimaker 3

We’ve received some reports on unstable Wi-Fi functionality on the Ultimaker 3 and Ultimaker S5, and we are currently researching a solution. If the Wi-Fi setup does not connect to your network, we recommend performing a factory reset and trying again. This will allow you to repeat the Wi-Fi setup so you can connect your printer to your network. Furthermore, a bug has been detected which may cause the screen of the Ultimaker 3 to distort / shift when using Wi-Fi.

Firmware 4.3.3

March 20, 2018

Extended language support. With the help of our community, we have extended Cura Connect’s language support in English, Italian, French, Spanish, German, Simplified Chinese, Dutch, Japanese, Korean, Russian, Portuguese, Turkish, and Polish, to make it accessible to users all over the world. Cura Connect’s display language is influenced by your browser’s language settings - to view it in another language, simply change your browser’s language.

Optimized JavaScript bundle.js. The size of the JavaScript bundle.js has been reduced to speed up Cura Connect’s page load time for a better user experience.

Material color and type. Now, jobs sliced for generic materials are printable on any grouped printer with a matching material type, regardless of brand or color. This brings the behavior in line with Ultimaker Cura’s slicing behaviour.

Pause, resume and abort. Jobs can be paused, resumed or aborted from within Cura Connect, giving the user more control remotely.

Job management. Previously, only jobs submitted from Ultimaker Cura’s “Print over Network” function were registered in the Cura Connect interface. In this update, jobs started from USB, and retry-after-fail jobs are registered, including the ability to view information, or abort.

Custom confirm dialogs. Previous versions of Cura Connect used default JavaScript dialogs. These have been replaced with a new custom popup component, to bring the language, look, and feel in line with Ultimaker Cura for a better user experience.

Mobile view. The mobile view has been optimized to show clearly on small screens.

Firmware version visible. The firmware version of each printer in a group is now visible on the printer details page, providing a centralized overview for users rolling out firmware updates.

Bug fixes

  • Updated tooltip content to clarify messages and fix spelling errors

  • Implemented new rules to prevent adding printers to groups they already belong to

  • Fixed various issues where group hosts could be ‘stolen’ and added to other groups

  • Fixed a bug where rescheduling jobs wouldn’t work after “move to top” or “override configuration” options

  • Stopped Microsoft Edge browser formatting IP addresses as phone numbers

  • Fixed a bug where on power-up Cura Connect would automatically restart the last object if the printer was powered off during the 'clear the build plate' prompt
