Retreat Cutting Time from Heidenhain Using TNCCmd

[JamesQ]

Hi,

     Can I have some advise on the interfacing methods (similar to Fanuc Focas, opensource or free if possible ) to extract data (cutting time, machine status etc.) from Mikron machines with Heidenhain controller? My main goal is to get actual cutting time for each NC program and daily machine running time.

      My current plan is to extract and filter machine log through TNCremo / TNCcmd, then treat these data using python text processing script. But I couldn't find much information online regarding TNCcmd commands and its script example. Appreciate if anyone here could share the example or idea to get these information. 

      Thank you.
