I have a AXYZ Z7 and would like to connect a mister to it but I really don't want to pay $2,500 for theirs. All I need is an air connection on the gantry and I can use any make and model. There is 4mm PTC (push to connect) for the pressure foot. There is also a 6mm PTC with nothing in it. Inside, the 6mm line runs to a solenoid valve that is powered by the PC board. Does anyone know what that 6mm PTC connector is supposed to be used for and how I can power the solenoid?

Searching for the installation manual, owners manual and about any other associated manual yields no pertinent information. I already tried Tools Manager/Tool Properties/Auto Mister and Air Assist. Any insight would be most helpful.
