I remain convinced that Toolpath is a very useful program for sending files to the controller and wouldn't advise exploring it's capabilities beyond that if you have access to a more recent CAM program.In a way,DNC is similar in that it sends the Gcode from the computer to the controller and doesn't involve the archaic process of toolpath creation that is packaged within Toolpath.It does have a certain nostalgia value in that respect.A full list of the various F functions is a handy thing to have and may impress you with the amount of control available with the machine.
