Summary

• New community translations
• Added LCD support for äöüß and μ
• SN check fixed
• Changes to on-screen messages
• Known issue (LCD glitches)

This is the final release of firmware 3.11.0 introducing additional language translations prepared by our community. Compared to the previous release candidate, there is one new community-translated language (Swedish) and the developers have done few fixes and improvements.

We would like to thank Prusa community members @AttilaSVK, @Painkiller56, @Hauzman, @Prime1910, @PRPA041, @ingbrzy, @shatter136, @pkg2000 who contributed to this firmware release.

New community translations

Due to multiple firmware optimizations, the developers were able to free up space and the first community language (Dutch) was added in the release 3.10.0. For this release we are further extending the list of languages:

• Hungarian by @AttilaSVK and @Hauzman
• Romanian by @leptun and @Hauzman
• Croatian by @Prime1910 and @PRPA041
• Slovak by @ingbrzy and @shatter136
• Swedish by @Painkiller56 and @pkg2000

We welcome everyone to join us and localize the printer to their native language. The translation procedure is designed to be easy and only basic computer skills are required. In case you would like to translate and maintain the translations, please visit this article describing community translations.

If you have any suggestions for the community translations please open a community GitHub issue and don’t forget to mention the language, the message/translation and if you know the maintainer also tag her/him with GitHub username. You can find the status and maintainers of community languages here. The community members are responsible to follow up your issues and prepare changes if needed for the next release.

Original Prusa MK2.5 and MK2.5S users will find the firmware in the provided zip files.

Disclaimer: Please note that community translations are made by the active community members and aren't further verified by Prusa Research, therefore some parts might be translated differently than originally intended.

Added LCD support for äöüß and μ

The German translation got an update and now shows messages with an äöüß instead of ä -> ae , ö -> oe, ü -> ue and ß -> ss. The only limitation is, that we don’t have uppercase ÄÖÜ so words and at the beginning of a sentence it stays in lowercase äöü. We believe that even with only lower case äöü words and sentences read better than before.

In Swedish we also added the support for äÄöÖ as in German above but characters with diacritics åÅ are replaced without the diacritics as aA.

SN check fixed

In firmware 3.10.1, we have added a motherboard serial number check, a function for future projects. If you have a genuine Original Prusa 3D printer, this does not affect the functionality of your machine in any way. However, in case you run into issues with the serial number check, please contact our tech support. In case you have purchased a non-genuine board this should be now fixed.

Changes to on-screen messages

We have improved and consolidated a few messages displayed on the screen which saved quite a bit of resources we can use for other features but also keeps the wording more consistent.

• Word Choose has been replaced by Select
• We have unified fan naming to: Extruder and Print fan. Nozzle fan has been removed.
• Renamed Temp. cal to PINDA cal. as this menu/feature might be misunderstood. The sole purpose of this feature is to calibrate the temperature drift of the PINDAv2 sensor. Note that SuperPINDA doesn’t need any PINDA cal. as it is temperature-independent.

Known issue (LCD glitches)

Some printers might experience LCD glitches, or random characters displayed during XYZ calibration. This has been discovered and reproduced recently and the affected printers are mostly MK2.5 and MK2.5S. Based on our observations for the MK3 family of printers this issue is rare.

The developers have identified the issue and are working on a solution. We are sorry for the inconvenience.
