Eny help?

thank

Hi Alessandro, that's odd!

I can see you have a folder named GRBL in Arduino\libraries\GRBL, try deleting it and re-downloading grblForCyclone (zip file). You only need to extract the whole Zip and open grblForCyclone.ino from the Arduino IDE, then select your USB and board type (from the "tools" menu) and finally click Upload.

Hope that helps!

Which electronic board are you using BTW?
Cheers,

Carlos
