PrusaSlicer 1.38.3

Slic3r Prusa Edition Slic3r 1.38.3 - Prusa Edition

Summary:

This is the Slic3r 1.38.3 - Prusa Edition release. This is a beta release, fixing bugs of the 1.38.2 alpha, and bringing some minor improvements.

This release contains the following improvements:

• Changed handling of filamentgcodestart and filamentgcodeend custom G-codes for a single extruder multiple material setup: At the start of a print, the filamentgcodestart is executed

for the active extruder only, and the filamentgcodestart / filamentgcodeend are later executed at each tool change. When the Prusa MM wipe tower is active, the tool changes are handled a bit differently: M900 K0 is emited before the wipe tower extrusions start, and the filamentgcodestart code is executed after the wipe tower extrusions are finished. This rule effectively disables the linear advance over the wipe tower #568.

• Removed an unnecessary restriction, which prohibited printing multiple objects, some with support, some with no support, on Prusa MM printers.
• Increased the fill rate of the support 1st layer from 50% to 70% to make the support 1st layer reliable.
• Added a new hot key 'a' to auto arrange objects in the 3D scene.
• A new command line --no-gui has been added to enable execution of a Linux AppImage Slic3r build as a command line tool, thanks @lordofhyphens #511.

This release contains the following bug fixes:

• Fixed a bug in the alpha build 1.38.2, which made Slic3r run on Windows only github.com/prusa3d/Slic3r/issues/594,https://github.com/prusa3d/Slic3r/issues/596. ↗
• Fixed a bug in supports with sheath: A support base of fully soluble supports is commonly printed with a sheath to make it more stable. There was a half extrusion width gap created erroneously between the support and the support sheath. Now the support sheath will overlap with the support base by 10% of the extrusion width to fuse reliably.
• Suppressed some warnings about unknown key accelerators on Linux #539.
