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 or SMC_ReadNCFromStream should be used, which contain the parser. It is not necessary to use this function block directly in most cases.
