the reason is quite obvious as the message explain that the tool data is missing. You found the reason. How to solve: Make sure the ini file is up to date and includes all needed tool data. When running internal NC code simulation based on operations the post of the OOTB data will create a proper to_ini.ini file.
I assume the NC code will simulate T1 M6.
Hope it helps
