# This file is a POST PROCESSOR for Robot Offline Programming to generate programs
# for a Universal Robot with RoboDK
#
# To edit/test this POST PROCESSOR script file:
# Select "Program"->"Add/Edit Post Processor", then select your post or create a new one.
# You can edit this file using any text editor or Python editor. Using a Python editor allows to quickly evaluate a sample program at the end of this file.
# Python should be automatically installed with RoboDK
#
# You can also edit the POST PROCESSOR manually:
# 1- Open the *.py file with Python IDLE (right click -> Edit with IDLE)
# 2- Make the necessary changes
# 3- Run the file to open Python Shell: Run -> Run module (F5 by default)
# 4- The "test_post()" function is called automatically
# Alternatively, you can edit this file using a text editor and run it with Python
#
# To use a POST PROCESSOR file you must place the *.py file in "C:/RoboDK/Posts/"
# To select one POST PROCESSOR for your robot in RoboDK you must follow these steps:
# 1- Open the robot panel (double click a robot)
# 2- Select "Parameters"
# 3- Select "Unlock advanced options"
# 4- Select your post as the file name in the "Robot brand" box
#
# To delete an existing POST PROCESSOR script, simply delete this file (.py file)
