I got the control panel pretty much finished for my supermax mill. Features are cycle stop/start buttons. Buttons to activate tuning on pixies and reset. E-Stop, Optical Drive, Media Reader w/USB, Hole for pendant connection, 4th axis connection, Mouse wheel and buttons, 15" LCD with ELO Intellitouch touch screen 1/4" thick glass, meter for showing spindle current draw. Made from 5052 Aluminum .080 thick and powder coated.
The touch screen works great. Have a wireless mouse attached but almost never use it. The only bad thing is the ELO method of right clicking sucks, so I used the guts out of an old mouse to add a scroll wheel and extra mouse buttons. Great for scrolling through gcode!
