On some versions of Mach4 there is a bug that does not allow you to change the Tool Change Type.  It will be stuck on T on M6 line is next tool.  This has been fixed in current Mach4 releases but you may run across this once in a while.

There are two fixes to this:

  1.  Update Mach4 to the current release.  Depending on custom programming, this may not be a viable solution.
  2.  Make sure Mach4 is closed.  Go into the profile folder and delete parameters.ini and sysvars.dat files.  Restart Mach4 and you should be able to alter the Tool Change Type.
