Here is an example Python post script, (PostScriptExample.py), for a programmable post-processor which sets following data:
•Linear/Rapid motion format
•Start/End block format
•Setting "[SEQ_PRECHAR]" variable
•Tool Change block format (different for fist tool change)
•File extension for "File Extension from Post Processor" option
from post_ext import *
# Set output file extension GENERAL_OutputFileExt = ".nc"
# Define block format for outputten code LinearMotionCodeBlock = "[G_CODE][DELIMITER][NEXT_X][DELIMITER][NEXT_Y][DELIMITER][NEXT_Z]" RapidMotionCodeBlock = "[G_CODE][DELIMITER][NEXT_Z]\n[NEXT_X][DELIMITER][NEXT_Y]" StartProcessingBlock = "[START_CHAR]\n[SEQ_PRECHAR][SEQNUM][DELIMITER]G40[DELIMITER]G49[DELIMITER]G80[DELIMITER]G98 - Start processing" EndProcessingBlock = "[SEQ_PRECHAR][SEQNUM][DELIMITER]M30\n[STOP_CHAR] - End processing"
