I will try
1. Under “Chavalier Mill --> NC Style, G-Codes and Modality --> Set Up Sheet
Turn ON the "Output Setup Header / Trailer"
2. Under “Chavalier Mill --> NC Style, G-Codes and Modality --> Code Constructors --> NC Program General --> Set-Up Header
Delete all the text in the output bar and plase the % symbol
3. Under "Chavalier Mill --> NC Style, G-Codes and Modality --> Code Constructors --> NC Program General --> Set-Up Trailer
Delete all the text and leave it empty
Then save it and compile. Then run out an code and check it
Good luck!
