Hey all,
I just picked up a Neoden3V and was using femtodev's script to convert a KiCad .pos file to a .csv for the Neoden. I wanted to be able to launch the script without the command line so with the help of OpenAI's GPT3 I modified the code to launch it as a gui that also shows the output directory.
I'm no coder and it's still a work in progress to please feel free to let me know if you have anything to add or that should be fixed.
Python script below:
# Ash's GPT3 KiCad to Neoden3V file conversion code | 5/12/2022
# This script is a modified version of femtodev's version of szczys's python script. It was edited (sucessfully)
# by OpenAI's GPT3 Chat dialog in around 5 minutes. This script remains a perpetual work in progress.
# Original script: https://git.femtostar.com/femtodev/kicad_to_neoden/-/blob/master/readme.md
from __future__ import print_function

#Paste relevant rows of the .pos files below and chance the trailing_letter
#to be "T" for top or "B" for bottom

I thought this might be handy for the few other Neoden3V owners out there. Please let me know if posting this is not allowed.
