PrusaSlicer settings are present in the live
directory. The structure is as follows:
live / {vendor name} / {bundle version}.ini
Each bundle contains complete configuration of relevant printers, filaments and prints options.
Along with them is an index file, which Slic3r reads and uses to find out which version is the newest compatible:
live / {vendor name} / index.idx
Slic3r downloads these setting bundles automatically (unless updating is disabled), and so there should be no need to install them by hand.
This project contains the Slic3r profiles for the 3D printers produced by Prusa Research https://www.prusa3d.com/
To apply these settings, you have to copy the particular github folder (Slic3r settings MK2, MK2S, MK2MM and MK3 / Slic3r settings 175 / Slic3r settings 3mm) into a local folder, where Slic3r will find it. The destination depends on your operating system and Slic3r version:
Slic3r PE 1.38.4 and later
All other versions
In case you installed the Prusa3D Windows drivers package, the Start menu is filled in with Slic3r shortcuts. These shortcuts are stored in "C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Prusa3D" and they point Slic3r to the particular settings folder using the --DataDir switch.
Therefore if you installed the Windows drivers package from Prusa3D, you may as well extract the whole (Slic3r settings to "C:\Users\Public\Documents\Prusa3D\".
