OK, I've finally got around to looking through Tormach's python code. The only relevant file seems to be
~/tmc/configs/common/namedparameters.py.

Possibly other parameters are defined elsewhere, in hardware-specific python routines, but the only parameters defined in namedparameters.py are

• _pi
  
• _epochtime
  
• _x_axis_min_limit
  
• _x_axis_max_limit
• _y_axis_min_limit
  
• _y_axis_max_limit
• _z_axis_min_limit
  
• _z_axis_max_limit
• _spindle_rpm_max
  
• _spindle_rpm_min

You also need to look in configs/<mill or lathe or router>/python. The toplevel.py e.g. has a lot of globals defined.
Toplevel.py specificlly states " build the following globals variables for the various atc ngc routines in remap" and although it mentions Remap, those variables are global so accessible elsewhere

I glanced at toplevel.py, but I didn't pay attention to the ATC-related stuff. I'll leave that digging to people with ATCs.
