I'm trying to create a custom post for ABB Welding that initiates a ArcLStart for the first point then ARCL instructions ending with an ArcLEnd.  Any suggestions would be appreciated.   Sample code I'm trying to generate above.  Thanks!

# This file is a POST PROCESSOR for Robot Offline Programming to generate programs
# for an ABB robot with RoboDK (compatible with S4 to IRC5)
#
# 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)

Hi Stefanie,

I attached a post that will allow you to have the target data inline with ArcLStart and ArcLEnd.
Let me know if you need any other changes. We'll make this post the default post in future installs.

Albert
