SMC_NCTokenParser (FB)¶

FUNCTION_BLOCK SMC_NCTokenParser

The parser between the SMC_NCTokenizer and the SMC_NCInterpreter. The parser transforms the stream of tokens to a sequence of g-code sentences ready to be interpreted.

Note

Usually, SMC_ReadNCFile2 is used which contains the parser. So it is not necessary to use this function block directly in most cases.
