Don't know if this will help but it comes from the stg.c file.  I notice that 
the stuff like lube, coolant and such are not assigned.

  Analog and Digital IO

  Analog and digital IO are mapped directly onto the board with no care
  that they don't collide with axes functions above. This is good in the
  sense that you can effect motion, bad in the same sense. This means that
  you should leave indices 0..axis-1 alone and use the higher indices for
  general-purpose IO. For example, if you have a 4-axis board and only
  3 real axes, you can use digital input at indices 12..15 for anything.

  Analog input is an option for the board. There are 8 inputs, which
  don't collide with any motion IO so you can use indices 0..7
  regardless of how many motion axes you have.

  If you have an 8 axis board, only 6 axis can be fully used for motion
  since there is not enough digital input for all the home and limit switches.

  For a 4-axis board, there are:
  24 digital inputs (includes limit switches and amp faults at 0..15)
  8 digital outputs (includes amp enables at 0..3)
  8 analog inputs (with option)
  4 analog outputs (includes amp outputs at 0..3)

  For an 8-axis board (6 motion axes max), there are:
  24 digital inputs (includes limit switches and amp faults at 0..23)
  8 digital outputs (includes amp enables at 0..5)
  8 analog inputs (with option)
  8 analog outputs (includes amp outputs at 0..5)

  Here's the actual map. If you aren't using some axes then their
  slots are up for grabs.
