Adding a post-processing script in Prusa Slicer for Mac

I am completely new to this and need to add the following script to my print to make fuzzy skin on the surface

i have installed Python 
 /Applications/Python 3.14/Python Launcher.app

And my script is located here
Users/casperschjorring/Downloads/Fuzzyficator.py

If I add it in as "/Applications/Python 3.14/Python Launcher.app Users/casperschjorring/Downloads/Fuzzyficator.py"

I get the following error:
Post-processing script /Applications/Python 3.14/Python Launcher.app Users/casperschjorring/Downloads/Fuzzyficator.py onfile /var/folders/dx/cp9zdnxj131_q21nhtjdn_t80000gn/T/.68526_0.gcode.pp failed.
Error code: 127
Output:zsh:1: no such file o r directory: /Applications/Python

What am I doing wrong

Unless I'm missing something in your post, can't you just use the fuzzy skin options in the slicer? Or does your script do something different?

RE:

Regarding the specific "fuzzy skin" application, I agree with @hyiger that the built-in fuzzy skin option is probably the way to go.

Regarding post-processing scripts in general, Prusa's help page explains that spaces in file and path names are allowed, but need to be escaped:

 If path to executable or arguments contain spaces, these arguments need to be escaped using the escaping style common to the platform (shell escaping style on Linux and OSX, Windows command line escaping).

The problem is that the build in fuzzy doesn't work op top of the print only the sides.

OK, then to make it work try this (two choices)

  • Either rename "Python 3.14" directory to "Python"
  • Or make a symlink 
    1. open a Terminal window
    2. sudo ln -s  "/Applications/Python 3.14" /Applications/Python
