4.2.0-RC1 Firmware for Original Prusa MINI

Detailed description

Firmware localized into 7 languages

Until now, the firmware for the Original Prusa MINI was available only in the English language. With this release, we are adding support for more languages. Apart from English, users can now also select:

• Czech
• German
• Spanish
• French
• Italian
• Polish

Compared to the previous generations of the Original Prusa i3 printers, the MINI is able to change the language instantly. Also, thanks to a better LCD screen, there will be support for diacritical marks in the final release of the firmware. The entire firmware uses UTF-8 texts.

There are two ways how languages can be selected:

• Via a prompt when the printer starts for the first time. This is a typical example of new printers leaving the factory and also if the firmware is updated to version 4.2.0. Once the language is set, the user won't be asked again, even after updating to higher versions than the 4.2.0.
• The other option is to change language manually. Go to LCD Menu - Settings - Language and pick the desired language. As mentioned earlier, the change is instant.

 
Examples of the user interface in German language

Integration of the languages is still in progress, diacritical signs will arrive in the final release. If you encounter any issues, please let us know.

Known issues:

• Some parts of the NTP server are not translated (e.g. Today, tomorrow, days of the week)
• On the Selftest screen, the text is wrapped incorrectly in all languages

Printer beeping in silent mode fixed

In case the printer was switched to silent mode, but the filament sensor was present and activated, the printer kept beeping when the filament was absent (e.g. filament runout). This is now fixed and the printer remains silent even when the filament runs out.

Supported printer:

• Original Prusa MINI
