Geoff,
When you unpack and install the KX3 it comes with an installation disk that automatically loads all the settings for the the machine including a new screen set and the icons for it.

This screen set coincides with the instruction book that comes with the machine. The screen set has been altered slightly so all the work can be done off the first screen including setting tools.

The buttons have also been altered hence the new icons to make them more manageable for touch screens. We use touch screens on all our machines, about 5 or 6. Some are capacitive and some are resistive depending on what came up cheap on Ebay !
Some you can use with a pointer, dead felt tip works well and the other have to use a finger and not even a finger nail, can't remember which way round it is though.

Between hot keys on the keyboard and the touch screen we never use the mouse. We are working on a better set of screens at the moment to enhance what is already there where buttons change depending on state like red for off, green for on and also changing legends that say on when on and off when off.

The idea is to get away from flashing and blinking lights that distract when machining.
