PrusaSlicer 1.40.1-beta

Slic3r Prusa Edition Slic3r Prusa Edition 1.40.1-beta

Summary:

This is a minor release, extending the firmware updater, showing the print bed image for the Prusa i3 MK2 & MK3 printers, improving OctoPrint integration, integrating the STL fixing service on Windows 10, and fixing some bugs.

This release brings the following new features:

• Extension of the firmware updater for the Prusa i3 MK3 Einsy board to upload language dictionaries into an on board 256kB flash memory. The on board 256kB flash memory will be used first by the Prusa3D firmware version 3.3.0-RC1 to store language dictionaries.
• For the Prusa i3 MK2 and MK3 printers, a picture of the real print bed is shown by Slic3r. Some may find it useful to mark spots on the MK2's bed picture to indicate damage of the PEI sheet #917. The print bed images are stored in resources\icons\bed and the correspondence of the images towards the i3 MK2 and MK3 printer models is hardcoded as of now.
• Object's selection is now mantained when rotating or panning the 3D scene view.
• Support for the NetFabb STL fixing service under Windows 10. This excellent cloud service is called by the Windows 10's own "3D Builder" application, and it is also offered through a Windows 10 programming application interface, which this Slic3r version now makes use of. Click on an object with a right mouse button to open a context menu, then select the new "Fix STL through NetFabb" item at the end of the menu. Please note, that this is a cloud service, therefore your object will be sent over the network.
• Improved OctoPrint integration. When sending a G-code to OctoPrint, a new dialog will open, where one may rename the G-code file, specify a target path, and let the OctoPrint to start printing when the file transfer finishes #55, #87, #245, #880.
• Improved loading of the AMF files. Slic3r will now detect whether the AMF file is zipped based on the content of the file. In earlier versions, Slic3r relied on file extension only (.amf -> unzipped, .zip.amf -> zipped).

This release contains the following bug fixes:

• Firmware updater on Windows was updated to support non-latin1 characters in the paths to the firmware hex file.
• Firmware updater recovery from communication errors was improved by lowering the timeouts.
• Fixed storing of rotation angles along the Z axis into a 3mf archive.
• Fixed the smooth variable layer height editing for multi-part objects.
• Fixed erroneous extrusions for the wipe tower rotated by 90 degrees.

The following internal changes were made:

• The 3D scene code has been ported from Perl to C++. This refactoring allows us to implement 3D manipulation gizmos similar to PrusaControl in the following releases.
