along these lines here is what we were thinking ( but have not done yet)
use the extra IO pins to create ic2 and or SPI communication ports, so that an arduino can send and receive any message to the printer via the peachy circuit and so that
the peachy circuit could posibly control things like LCD screen, button panel etc.

What we do have working now is the peachy software sending commands thru a separate serial port, this is how we do our time lapses of prints an arduino is instructed to open the shutter while the laser drawing 1 layer. We also have send codes to the arduino to turn the peristaltic pump on and off, or whatever else we want.
