    • 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

    This doesn’t work after Cura 4.1 - can you update it please?

  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.

    • On Mac open the Finder, press "Command+Shift+G" and enter "~/Library" (without quotes)

    • The path can slightly differ, for example, if you have a different version of Cura installed. Also on macOS the "Library" folder is hidden.

    • Copy the file(s) "...def.json" from the package to the Cura folder.

  6. From now on the steps are the same both for MS Windows and Apple macOS.
    • From now on the steps are the same both for MS Windows and Apple macOS.

    • 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.

    “Original Prusa i3 MK3/MK3S” does not show under “Other” for me. I followed all instructions correctly and even tried a fresh install and tried again with same result.

    I had a bit of trouble finding my i3 mk2.5S because of the confusing naming scheme Prusa decided to use in the printer listing. You really should make all Prusa printers appear in the P section instead of having them divided between the O and P sections.

    mechaMecha - Reply

    Helo, thanks for your comment, we’ll see what can be done with that.

    Martin L. - Official Prusa CS -

    Hi mechaMecha,

    our printers are called Original Prusa i3 and since we are open source there are clones, which are missing the “Original” in its name. Therefore all the profiles Prusa i3 … are done either by users, or by creators of the given software. Only profiles named “Original Prusa i3” were done officially by our company.

    It will be under Prusa Research now in the Cura “add printer" page

    On MacOs Mojave, I was running into an error when opening Cura after “verifying” the application that it was damaged. I assume this was from copying the mesh into the application contents. I fixed this by running the following command:

    I see, please ignore all the _MACOSX files, those are some “remains” if the package was zipped using macOS. However, I just downloaded the package from our site, where these _MACOSX files were removed before uploading the package and I can't see them on Windows. Can you please re-download it again?

    Why is the retraction distance not the same in the PETG profile for Cura, than the one in PrusaSlic3r?

    (in Slic3r there is a filament override for 1.4mm retraction, which is not defined in your Cura profile, it’s set to 0.8mm)

  9. Before you slice and print, lets make a final check:
    • Before you slice and print, lets make a final check:

    • Your printer is selected (e.g. Original Prusa i3 MK3S).

    • The desired material is used (e.g. Prusament PLA)

    • Correct custom profile is applied (e.g. 0.2 Fast for MK3S).

    • That is all! Enjoy your printer and happy printing ;)

    • You can discuss your experience and print results on Prusa Research forum.

    now the actual version of Acura is 4.4.0, it asked me right away, which printer I want. I choosed Prusa MK3S, the Software started right away. Do I still have to import the data for the “Original” Prusa like described?

    Hi Michael.

    Yes, if you don't see the option to select the "Original" Prusa i3 profiles, then you must follow these instructions.

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

Andreas - Reply

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!

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,

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”.

are these profiles for the original prusa printers or do i still have to manually install the “original prusa Mk3s” profiles as mentioned above?

Hey! is there any way to show the time remaining of a print and the percentage that has been printed, or is that a feature that will be added later. Currently when i print using cura the lcd says SD: 100% and 00:00 for time.
