To help us determine if this is a problem with Inkscape or with the third-party extension, or with your Inkscape installation, please answer the following questions:

- have you uninstalled Inkscape completely and made sure that this has deleted all its files before you reinstalled it? If not, please try that first and let us know what happens when you try it again afterwards.

- please share a file and the exact steps to reproduce the issue (where do you click, what options do you select)
(you can append attachments to your comments here, 1 per comment)

Hi

I think this is the same bug as I experience on Ubuntu Bionic. There's a directory parsing string error message. Either you type a directory, and laser.py claims it doesn't exist, or you leave it blank in which case it fails to write the gcode file:

Traceback (most recent call last):
  File "laser.py", line 3173, in <module>
    e.affect()
  File "/usr/share/inkscape/extensions/inkex.py", line 283, in affect
    self.effect()
  File "laser.py", line 3170, in effect
    self.laser()
  File "laser.py", line 3032, in laser
    self.check_dir()
  File "laser.py", line 2554, in check_dir
    if self.options.directory[-1] not in ["/","\\"]:
IndexError: string index out of range

This only occurs with the plugin. Have emailed Photonics to let them know. If anyone has a quick work around please let me know - maybe commenting out the directory path check?

You could just try it out, and report back if it worked.

Hi,

I found this post because I had the same error and it's the top Google result.

If I specified a directory for the output file it was all good. I think it's the blank default path which gives rise to the error, there is no last character in an empty string.

Closing: The bug is not within Inkscape, please complain with the author of the original plugin.
