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, diacritical marks are now supported. The entire firmware uses UTF-8 texts.
There are two ways to change the language:
- 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 the language manually. Go to LCD Menu - Settings - Language and pick the desired language. As mentioned earlier, the change is instant.
Known issues:
- Error texts in the “red screens” remain untranslated, this part of the firmware is currently undergoing a major update, planned for the upcoming release
New sound volume option
The previous firmware release 4.1.0 introduced sound profiles (Loud, Once, Silent and Assist) known from the Original Prusa i3 family. In this release, we are expanding this feature even further. Not only are you able to change different sound modes, but also the volume.
If the user finds the warnings too loud or too quiet, it’s possible to adjust the volume on a scale from 0 to 10 through Settings - Sound volume. The default value is 5.
Pause print from USB (M601) fixed
The latest stable firmware 4.1.0 ignores the M601 G-code, which is supposed to pause the running print. This function is useful, for example, when you plan to embed magnets into the object during the print.
This issue is now fixed while printing a G-code generated in PrusaSlicer from a USB drive. Note that M601 is currently not working for OctoPrint and Pronterface, it will be addressed in the future firmware release.
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.
