Hi al, hopefully I can get some help here and get this issue resolved. Trying to get my wife onboard with linux. She has a Silhouette Cameo and using inkscape 0.92.1 and Ubuntu 16.04, I installed the extension "export/send to silhouette". Typically the first time opening the app it will send to the cameo, there after, it will no longer work, continually getting the error message:

Inkscape has received additional data from the script executed.
The script did not return an error, but this may indicate the results will not be as expected.


Any help on whats going on with this and what I can do to fix it. Would love to be able to not have to go back to using windows for this.

Thanks.

(edit) Would you please tell us where you downloaded from? I can't test myself, but someone might want to. Or someone might like to try and fix it.

When you mention not going back to Windows, do you mean that the extension works properly on Windows?

Edit #2
Also you could check and make sure you have the current version.

I suspect the author of the extension would be able to fix the issue. Can you contact them and ask for support?

I went thru http://www.instructables.com/id/Inkscape-Silhouette-UbuntuRPi/ for the download and installation steps.

My desktop computer runs linux while my kids have laptops with windows on it. Would rather use desktop Linux as its much faster, but if I cant get this to work, may have to use the laptops for this instance.

Yes, may try to contact the author and see if they can help
