Testing gcodepreview and application versions

[WillAdams]

Currently running: OpenSCAD version 2024.12.29 (git ) using the command

"C:\Program Files\PythonSCAD\bin\openscad.exe" --trust-python

Have a working file:

gcp_dovetails.zip

but when I tried to Design | Share design got:

Currently loading the library with the code:

try:
    if 'gcodepreview' in sys.modules:
        del sys.modules['gcodepreview']
except AttributeError:
    pass

from gcodepreview import *

and things work, loading from: "C:\Users\willa\OneDrive\Documents\OpenSCAD\libraries\gcodepreview.py"

When I comment that out and try:

from openscad import *

nimport("https://raw.githubusercontent.com/WillAdams/gcodepreview/refs/heads/main/gcodepreview.py")

things also work as expected (and that is the version which it would be best to have shared).

Next up, updating the application and testing again.

Ahh this is why, will have to check

[gsohler]

I was able to submit without hazzle

I will try to chech the weblogs to get an idea why it could go wrong

[gsohler]

your design was actually correctly uploaded. need to find out, why it output an error

[WillAdams]

Probably the old version.

I downloaded the new one, and will install it next and write up how it goes presently.

Downloaded:

https://www.pythonscad.org/downloads/PythonSCAD_nolibfive-2025.04.13-x86-64-Installer.exe?

and installed adding to the path:

in the default location:

which completed successfully.

Edited the icon to point to the binary and add the trust command:

(and also changed it to put new files on the Desktop --- not sure why I never thought to do that before)

Launched as expected:

and once again we are at:

Running Python 3.11.5 without venv.
ERROR: Traceback (most recent call last):
File "", line 1, in
ModuleNotFoundError: No module named 'gcodepreview'
Traceback (most recent call last):
File "", line 141, in
NameError: name 'gcodepreview' is not defined

this with a version which uses nimport:

from openscad import *

nimport("https://raw.githubusercontent.com/WillAdams/gcodepreview/refs/heads/main/gcodepreview.py")

editing back to use:

try:
    if 'gcodepreview' in sys.modules:
        del sys.modules['gcodepreview']
except AttributeError:
    pass

from gcodepreview import *

we get:

Running Python 3.11.5 without venv.
ERROR: Traceback (most recent call last):
File "", line 135, in
ModuleNotFoundError: No module named 'gcodepreview'

Execution aborted

which is back to where we started.

If I load "gcodepreview.py" directly and run it, it works as expected:

as noted, the file is at:

"C:\Users\willa\OneDrive\Documents\OpenSCAD\libraries\gcodepreview.py"

and compiled successfully to:

"C:\Users\willa\OneDrive\Documents\OpenSCAD\libraries_pycache_\gcodepreview.cpython-311.pyc"

So I guess the question comes down to how accurately log/report this inability to access, and how does one grant access, and how does one edit/review a list of trusted files?

As noted before, I'd like to see a menu entry: File | Python | Show trusted files which would allow adding and removing files from that list.

Also tried Design | Load Shared Design:

which imported the file into a new Untitled.scad file and so errored:

re-saving as Untitled.py got the same thing:

This is great news, Thank you for reporting. Not all things can go wrong at the same time :)

Unfortunately, the post was made prematurely, and I've subsequently edited it.

Please advise on what I can do to check things.

Running:

# importing module
import sys

# printing all directories for 
# interpreter to search
print(sys.path)

yields:

Running Python 3.11.5 without venv.
['C:\Program Files\libraries\python:C:\Users\willa\OneDrive\Documents\OpenSCAD\libraries:C:\Users\willa\OneDrive\Desktop:', 'C:\Program Files\PythonSCAD\python311.zip', 'C:\Users\willa\AppData\Local\Programs\Python\Python311\Lib', 'C:\Users\willa\AppData\Local\Programs\Python\Python311\DLLs', 'C:\Users\willa\OneDrive\Desktop', 'C:\Users\willa\OneDrive\Desktop\Lib', 'C:\Program Files\PythonSCAD']

which seems right.

Tried to force the path with:

sys.path.insert(0, 'C:/Users/willa/OneDrive/Documents/OpenSCAD/libraries/gcodepreview.py')

from gcodepreview import *

but still get:

Running Python 3.11.5 without venv.
ERROR: Traceback (most recent call last):
File "", line 137, in
ModuleNotFoundError: No module named 'gcodepreview'

so I think we're back to something odd in Windows 11 and Python 3.11 running in it --- let me know what else can be tried/researched at my end.

Hi Wiliam, I work in linux most of the time, so I did not see the problem in windows But now I tried and i could reproduce The problem is that i used the Colon character as separation character to of the libs and in windows it appears the Semicolon is needed So it happened, that paths glue together in bad ways like "C:\Program Files\libraries\python:C:\Users\guenther.sohler\Documents\OpenSCAD\libraries:" <- this is one path You can fix temporarily in your place by typing: sys.path.append("C:\\Users\\willa/OneDrive\\Documents\\OpenSCAD\\libraries") (hope i copied the path correctly) (please note the double backslashes) The error which i am getting then is only: ERROR: Traceback (most recent call last): File "<string>", line 149, in <module> File "C:\Users\guenther.sohler\Documents\OpenSCAD\libraries\gcodepreview.py", line 1340, in opendxffile self.dxf = open(self.dxffilename, "w") ^^^^^^^^^^^^^^^^^^^^^^^^^^^ PermissionError: [Errno 13] Permission denied: 'aexport.dxf' It will be easy to you to resolve this issue

Thanks!

(figured it was something like that)

Obviously, I need to work out a better way to manage whether or where the .dxf files are getting exported (or set the default to not create them).

I'll probably just go back to the older version I was using until you drop an update --- no hurry.

Or just use the provided command, which worked perfectly:

and defer any production releases until the application catches up.
