I am having the same problem on my SuSe Linux system since the last update.
Before that, I have used dxf2gcode many years without trouble.
Problem also occurs with an older (2016) version of dxf2gcode.
Can I do anything to assist you in removing this prolem?
Thanks,
Martin

I am not sure where this issue is coming from. I commented the lambda function out. Please try to replace the file shape.py with the attached one and give me feedback if that works or the new failure message you get.
Christian

[Martin Oppermann]

Hi Christian,
thanks for the file,
I tried the attached shape.py, but no success: same error message (attached).
best regards,
Martin

[chrisko]

Stange, this part of the file should be commented out. Now i created a new one, which fully commented it out.
Please try again and ensure that you overwrite the existing shape.py.
regards
Christian

[Martin Oppermann]

Hi Christian,
thanks, but still the same... (error message attached).
regards,
Martin

[chrisko]

OK, i still don't understand it. Can you please check your python version and pyQT version. You may run a too new one. Please try to deinstall and run with the versions described in the README ( A short snapshot of the important ones ....)

• Runtime dependencies:

  • /usr/bin/python3 (>=3.5),
  • PyQt5 (>=5.7),
  • PyOpenGL (>=3.1),
  • configobj (>=5.0.6),
  • /usr/bin/pdftops (>=0.45),
  • /usr/bin/pstoedit (>=3.70).

  Note: Depending you used operating system flavour different package names
  might provides required dependencies...

  Note: Please do not install python3 version 3.7.x as at the time of writing
  there is no pyqt5-tools package available for this version of the python.

[Martin Oppermann]

Ok, I will try that on monday.
I have to find out how to downgrade python from 3.7 to 3.5 on tumbleweed.
Seems to be not so easy, only the newest packages are available with direct acccess to the repo via YAST.
Thanks and best regards,
have a nice weekend,
Martin

[Martin Oppermann]

Hi Christian,

sorry for the delay... The last weeks I tried to downgrade python to 3.5 on my SuSE Tumbleweed, but without success. It seems, only the newest packets are availale for tumbleweed. So I tried to install python 3.5 manually. That python version alone is running well, but it will not find the matching python toolkit things like Qt5 OpenGL etc. And for also manually installing these additional things, I don't have the knowledge (or the time to find out how everything fits together).

So it seems, I am lost :-(

Or do you have any other idea how to make dxf2gcode running on tumleweed?

Ain't there a possibillity in linux to make a dxf2gcode package including all needed libraries so it doesn't have to use anything that is outside its own environment?

Thanks,
regards,
Martin

Martin,
I was able to get it to run on 3.7 with a small edit in Shape.py. On line 605 where it calls "raise StopIteration()" I simply commented that out and called "return" and it's working.

[Martin Oppermann]

Hi Nick,
thanks for the hint, I just tried it.
It then crashes inside layercontent.py when saving the gcode file..... :-(

But I also commented out the StopIteration there (line 148 and 155), and then it seems to work.
No idea if this solution makes problems under some circumstances, but it works for the moment.....

[Damian Wrobel]

Should be fixed by https://sourceforge.net/p/dxf2gcode/sourcecode/ci/664248145862f00b6f49da6202f48c39895ceec8/

Please try using that version. In case it still doesn't work for you please attach an example causing the problem.
