#73 creating finish toolpath error
Suddenly, when trying to generate a finishing tolpath from an stl, I get the following error message. Rough toolpath works fine, nothing changed since last time I used Pycam.
An unexpected exception occoured: please send the text below to the developers of PyCAM. Thanks a lot!
