I found the reason !!!
Inside the Javascript file there are 8 lines with Chinese letter.
Topic: Preset - variable: name - don’t know what the meening is.
I changed it into englisch words (just china1 - china8) - and now it works !
Seems, that Fusion360 German Version don’t like Chinese letters.
There are 2 possibilities:
- It’s only a problem of the German version – or
- Nobody tried to use Fusion 360 for CNC (even the Snapmaker people)
