I'm thinking you should be looking for Ajax tech support. Or at least a security system forum.

Anyways seeing this again I have to add this correction to my previous post..

While the tft v3.0 screens do have a bunch of inputs the problem is the serial connection from the screen back to the board is not exactly a solid connection. For example, if your printer is connected to a pc via usb cable then your screen is likely not communicating in tft mode. And so wifi, ups 12v or 24v, filament runout sensors, and everything else should go on the mainboard directly and setup in the primary firmware. For the best results.
