Post-processing script not running
hi all..
i have a python script that run fine in cura.
can prusaslicer does this also?

would this be possible?

In Print Settings > Output options you can call a post process script.
... but don't expect Cura specific code to complete without porting.
Cheerio,
RE: Post-processing script not running
i did call to this script but slicer give error cant find script.
RE: Post-processing script not running
its normal python script mabe someone can port?
You need to give the path to the script just as you would with any other program and the file permissions may need to be set.
I don't know which operating system you are using but it may be something like: ~/3dfiles/myscripts/myscript.py
- and it looks like your script imports a library; it would be best to contact the author of the library who might have, or be working on, a port.

Cheerio,
i use Windows 10 64 bit so i cant set permissions right?
thx for reply
I haven't used Windows seriously this century ... but I'm pretty sure they use permissions still, hang on, yes:
A search for 'windows 10 file permissions' turns up some potentially useful pages.
Cheerio,
