Neat that you're making progress on this!

I approached it from a rather different perspective and instead used
RapCAD for G-code generation:

I've been documenting it at:

and have been using it inside OpenSCAD Graph Editor:

I thought there may be some interest in how it was proceeding, following
on from a previous thread.

I've patiently gone through 33 iterations of trying the batch file

results. It eventually seems to get into a loop, repeating previous
guesses.

This is the input file  (just one line)

M 10,-10 L 60,-10 L 60,-60 L 10,-60 z

The output that I want which should be

G01 Z-5
G01 X10 Y10
G01 X60 Y10
G01 X60 Y60
G01 X10 Y60
G00 Z2

I think the closest it has got is the following batch file

@echo off
setlocal enabledelayedexpansion

set "inputFile=input.txt"
set "outputFile=output.txt"

if exist "%outputFile%" del "%outputFile%"

for /f "usebackq delims=" %%a in ("%inputFile%") do (
    set "line=%%a"
    set "firstM=1"
    for %%b in (!line!) do (
        if "%%b" == "M" (
            if "!firstM!" == "1" (
                echo G01 Z-5 >> "%outputFile%"
                set "firstM=0"
            )
            set coord=
        ) else if "%%b" == "L" (
            echo !coord! >> "%outputFile%"

            echo G00 Z2 >> "%outputFile%"
        ) else (
            for /f "tokens=1,2 delims=," %%x in ("%%b") do (
                set y=%%y
                set /a y=-1*!y!
                if not defined coord (
                    set coord=G01 X%%x Y!y!
                )
            )
        )
    )
    if defined coord echo !coord! >> "%outputFile%"
)

endlocal

it does not show the Y values, although in earlier attempts it did, but
produced other errors.

It is a test, as far as I'm concerned, for the capabilities of AI.
However, although it has produced a batch file that almost does the job, it
does not seem capable of going the final mile, so to speak. When you sort
of get down into the weeds, it says it understands what it has done wrong,
says that the following script corrects the error, but then the script is a
repeat of the previous one. I'm not sure whether to push it further. It is
relatively trivial for me to write a bit of c++/whatever, to solve this
task, but trying to get the AI to do it is my current interest. Maybe it is
better at Python.

I write as little as possible in batch files. Python is a much better
language and works on all platforms.

I'll get it to try Python. It says it can. If it struggles, maybe you or someone else can jump in. I've modified Python code, slightly, but never done anything from scratch.

Well, it seems better on python.

I asked :-

'using Python, write the code for the following.    Given an svg file with the following line

M 10.7,-10.5 L 60,-10.5 L 60,-60 L 10.7,-60 z

generate the code to convert it to a gcode file, which should be

G01 Z-5
G01 X10.7 Y10.5
G01 X60 Y10.5
G01 X60 Y60
G01 X10.7 Y60
G00 Z2

basically, the M becomes
G01 Z-5
G01

the L becomes
G01

the z becomes
G00 Z2

the numbers stay as they are, but the one after the ',' is negated

The input file may have upper/lower case letters, and extra or fewer spaces and many similar lines'

and after about a dozen corrections, (at least three or four of which were me asking how to run python, it came up with

def svg_to_gcode(svg_line):
    # Split the line into a list of commands and coordinates
    svg_line = svg_line.strip().split()
    gcode = []
    for item in svg_line:
        if item.upper() == 'M':
            gcode.append('G01 Z-5')
          #  gcode.append('G01')
        elif item.upper() == 'L':
            if not gcode[-1].startswith('G01'):
                gcode.append('G01')
        elif item.upper() == 'Z':
            gcode.append('G00 Z2')
        else:
            # Split the coordinates and negate the second one
            x, y = item.split(',')
            y = str(-float(y))
            if not gcode[-1].startswith('G01'):
                gcode.append(f'G01 X{x} Y{y}')
            else:
                gcode.append(f'G01 X{x} Y{y}')
    return '\n'.join(gcode)

def convert_svg_file_to_gcode(input_file, output_file):
    with open(input_file, 'r') as f_in, open(output_file, 'w') as f_out:
        for line in f_in:
            gcode = svg_to_gcode(line)
            f_out.write(gcode + '\n')

Example usage

convert_svg_file_to_gcode('input.txt', 'output.txt')

which I save as ' line1.py' and run with the command 'python line1.py'  and it works, but have to test more thoroughly. I'd heard others say it was sort of OK with Python. However, it did get itself into an error loop, wrt the G01 being on separate lines, but I managed to break it out of that.

Now to see, if the other components, written as batch files, are easily converted to python, and discard the 50 or soother failed versions

For those that may be interested, I've attached the final python code that
ChatGPT wrote. All I did, was ask how to do whatever, along the lines of my
previous post. I never told it to use regular expressions - I've never used
them myself, but it will explain their use. i then asked if making a GUI
was possible, and it did that, then modified it into two columns, etc. when
I asked. It is quicker to ask it to rewrite the whole code, compared to me
altering selected limes, which is prone to errors.

This was a far better experience compared to getting it to write openscad
or batch file scripts.

Thanks, Chris, for the Python suggestion. It works really well with
ChatGPT.
