Example Script

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"

 

FirstToolChangeCodeBlock = ("; First Tool Change\n"

"[SEQ_PRECHAR][SEQNUM][DELIMITER][OUTPUT_UNITS_CODE][DELIMITER]T[TOOL_NUM][DELIMITER]M06",

"[SEQ_PRECHAR][SEQNUM][SPINDLE_BLK]",

"[SEQ_PRECHAR][SEQNUM][DELIMITER][OUTPUT_MODE_CODE][DELIMITER][G_CODE][DELIMITER]X[NEXT_NONMDL_X][DELIMITER]Y[NEXT_NONMDL_Y]",
