understand the classic ladder

I'm a student , I like to do small cnc with tool turrent as a project. I think classic ladder handle all the mcodes in nc file. Anyone please explain me source code flow from m-code from nc file to classic ladder and to machine level. Is any documentation available to understand the flow of the emc source code.

thanks

No one here to reply:angry:

If you are looking to control a tool turret using user m codes and classicladder see the manual,
then ask specific questions.
www.linuxcnc.org/docs/2.4/html/

unfortunately there are no good docs on the complete flow through the source code of EMC
Keeping in mind EMC is really a bunch of programs working together.
Classicladder is actually a total seperate program from EMC but is connected through EMC's HAL
interface.
I know there are some rough/old code notes somewhere....
