Linux is on the CD. It is supposed to be that simple, to just do
the install.

Yes, once it is installed, you DO have to go into the rather extensive
.INI file and make changes to tell it about your machine (stepper
resolution, max feed rates, max acceleration, travel limits, etc.)
You will have to learn how to use their text editor, too.

Coolant and spindle control are already there. There will be a parallel
port line that goes on for each of these functions.
Now, for tool changers, that gets more complicated. there are people
working on a ladder-logic or some other scheme for entering the
control logic for tool changers, auto lube systems, etc.

Depending on where you are, the NAMES show near Detroit might not
be too far.
