I installed the extension Raster2 Laser Gcode

but once opens the windows there is the following error and I'm unable to produce a gcode of the Raster image

Is it a problem of compatibility of the extension with the version of Inkscape ?

Does exist other extensions able to codify gcode of a raster image ?

Thanks a lot

Ho provato anche a scaricare Inkscape 1.0 appimage senza dover fare una nuova installazione. Ho installato i file dell'extension nella directory user extensions. Nel menu mi compare la voce Raster2 ma cliccandoci sopra non mi apre neppure la finestra di dialogo....

This extension is last modified in 2019. Later versions upgraded Python from 2.x to 3.x (and there are some other API changes). Basically, if it's not updated, it isn't compatible anymore. If you have some developer skills, you could look into it and pick it back up.

These pages could be of use:

Thanks Jurgen. If this is the situation my other questions are:

1) If I installed a version of inkscape older can I arrive to use also raster2 extension?

2) Do exist other tool that can allow to translate a raster image into a gcode for laser engraving ?

Thanks a lot

Kind regards
