Note:

• Code marked with * are codes that must be or are selected in the initial state
• Code marked with . are codes that should be or are selected in the initial state by the parameters
• If two or more G Codes from the same code are commanded, the later G codes will be valid
• This G code list is a list conventional G codes,Depending on the machine, movement that differ from the conventonal G codes command may be included when called by the  G Code Macro, and please refer to the instruction Manual issued by the machine maker
