I uninstalled inkscape and all the extensions and i started fresh again. I was using the Standard installation for mac as stated in the webpage but after your post i installed it manually and i advanced a little bit now it seem i am missing something called serialposix
Traceback (most recent call last):
File “wcb.py”, line 37, in <module>
File “/Applications/Inkscape.app/Contents/Resources/share/inkscape/extensions/serial/__init__.py”, line 21, in <module>
from serialposix import *
ModuleNotFoundError: No module named ‘serialposix’
Should i install also the axidraw extension?
