3.11.0-RC1 Firmware for MK3, MK3S, MK3S+, MK2.5 and MK2.5S is released.

Hello all. We are happy to announce our latest firmware release candidate, 3.11.0. Please see the updates below. 

Summary

• New community translations
• Added LCD support for äöüß and μ
• Known issues

This is the first release candidate of firmware 3.11.0 introducing additional languages translated by the community. We would like to thank Prusa community members @AttilaSVK, @Painkiller56, @Hauzman, @Prime1910, @PRPA041, @ingbrzy and @shatter136 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

We welcome everyone to join us and localise 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 suggestion to 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:

• English + Romanian end with ..._en-ro.hex
• English + Hungarian end with ..._en-hu.hex
• English + Croatian end with ..._en-hr.hex
• English + Slovak end with ..._en_sk.hex

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.

Known issues

In the 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. 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, please be patient or downgrade the firmware - a fix is currently being tested and we plan to include it in the next release.
