    • The following guide will help you import and activate custom profiles tweaked by Josef Prusa for your Original Prusa i3 printer.

    • This guide is valid both for Microsoft Windows and Apple macOS. There are some small differences in the setup, pay attention to the instructions ;)

    • Important: latest profiles include settings for generic PLA, ABS, PETG as well as Prusament.

    • Supported printers:

    • Original Prusa i3 MK3S and MK3

    • Original Prusa i3 MK2.5S, MK2.5 and MK2S

    • Click here to download the Cura package

  2. The package includes several subfolders, which must be imported (or copied) into the Cura. Note you have to use correct version of the settings! Folder 01_Cura_printer_definitons includes profiles for the printers with dimensions, speeds and other parameters.

    • Folder 01_Cura_printer_definitons includes profiles for the printers with dimensions, speeds and other parameters.

    • Folder 02_Cura_printer_extruders additional parameters for the printer, specifically for the extruder properties (new in Cura 3.5.1).

    • Folder 03_Cura_meshes includes platforms (heatbeds), which are just for the visual effect, though it is good to know, where your object will be printed on the heatbed.

    • Folder 04_Cura_layerheight_profiles includes settings for various layer heights (print quality).

    • Folder 05_Cura_Prusa_materials includes materials, which should be imported because default Cura material values differ from what is recommended for Prusa filaments.

    • File Readme.txt summarises changes to this package.

  3. By default Cura list of printers does not include Original Prusa i3 models. Let's fix it ;) First, save your work and close the Cura software.

    • Now, open the Cura software

    • In case you run the software for the first time, you will be asked to Add a printer, in the list click on Other and select yours.

    • Use only profiles named "Original Prusa i3...", those are developed and tested by our company. If the printer name is missing the "Original" in its name, then it is from different manufacturer.

    • In case you are already working with Cura, go to Settings -> Printer -> Add printer and select yours.

    • Cura allows you to add one printer at a time. If you want to add more printers repeat this step.

  7. Go to Settings -> Profile -> Manage Profiles Click on the Profiles and Import. Find the profiles on your drive (folder 04_Cura_layerheight_profiles), select one and open it. Unfortunately, Cura doesn't support multiple profiles import at once.

I assume this is for 0.4mm nozzle only, do you have support files for 0.25mm and 0.6mm too? especially 0.6mm. Thanks

Hello Andreas,

Unfortunately we do not have these. You can adjust the settings manually or switch to our Slic3r Prusa edition which of course fully supports these nozzle sizes and has plenty of other handy features!

Martin L. - Official Prusa CS -

was forced to use cura due to Slic3r Prusa edition failed to slice an easter egg properly, namely this one with the bunny inside

https://www.thingiverse.com/thing:354262...

slicer added weird infills a little bit throughout the inside of the egg shell to the bunny.

Have a look for yourselves.

Cheers,

Andreas

Hi Andreas, that looks to be an error in the model - but I’ll forward it to our Slic3r team to investigate it.

The profiles won’t import. Cura shows the success message but the profiles don’t appear under “custom profiles”.

Found this in the log:
