Firmware 1.3.0-FINAL for Original Prusa SL1

Hi guys,
this is a final version of the firmware recommended to all users 😎 Note that this update is sent primarily via OTA (over-the-air). Before flashing the firmware manually, check your internet connection on the SL1 first.

Summary

• New network management
• New update system (OTA)
• Localized user interface
• User resin calibration
• Improved graphics in Wizard/Calibration
• Printer not calibrated warning at startup
• Phantom click resistant UI
• Others
• Fixed bugs

A detailed description

This is a major firmware release with important changes both to the functions (user interface) and backend (not visible to the user). There are also multiple updates to the code setting a basis for the upcoming functions and features in the future firmware releases.

New network management

The connection to the network (LAN and Wi-Fi) is now managed by a brand new Network Manager. The user interface was vastly updated to provide more details about the currently connected network, enabling new features and easier troubleshooting, for example:

• static IP address input
• custom DNS servers
• hidden SSID networks
• forget network settings/logins

New update system (OTA)

Starting with 1.3.0 firmware we are introducing a more robust update system. If the printer is connected to the internet, it will periodically connect to the server and ask for new updates. As soon as the new firmware is available, the user will be notified on the screen.

Part of the new update server is improved updates distribution. We have implemented downloads using the content delivery network (CDN) with data centres across the entire world. Therefore if you are located for example in the USA, your update will be downloaded from a US server resulting in higher download speeds.

Localized user interface

The SL1 UI is now available in English, but starting with 1.3.0 user can choose from other supported languages (Czech, Italian, Polish, German, French and Spanish). The language selection will appear after the update, it can be also accessed by going into the Settings -> Advanced settings -> Set language.

User resin calibration (fine-tuning)

We are continuously testing and growing the number of supported resins for the SL1 printer. Starting this release, we are adding an option for experienced users, who are using special resins and would like to tune their settings.

Part of the "examples for the download" is a new file for resin calibration. If a user selects this file for a print, the system recognizes it and starts the resin calibration procedure. The calibration object will be printed eight times with different exposure times (set by the user) allowing to evaluate the print results and select the exposure time, which brings the best result for a given resin. An article with a detailed procedure will be soon available at help.prusa3d.com.

Improved graphics in Wizard/Calibration

The pictures in the Wizard and Calibration guides were updated to match the latest printer design and are now utilizing the entire size of the screen for better clarity.

Printer not calibrated warning at startup

In case the calibration procedure is skipped the printer will notify the user upon each start until the procedure is initiated and finished.

Phantom click resistant UI

The user interface for the most critical control functions like starting or cancelling a print was redesigned to be more resistant against phantom touches, which might happen in rare scenarios with a dirty touchscreen.
