It's not that it can't be done. It can. But I don't think you're considering the whole process as a complete machine. If all you were doing was controlling functions where precise timing wasn't needed (turning on a fan, light, heater, etc) then yeah, you could use it to expand. But once you get into controlling steppers, things get a lot more complicated as steps between motors needs to be timed precisely, something I'm not sure i2c would be good at.Quote

i don't think it would be that much of an overhead as the expansion board will have a few commands to deal with.
pretty much, turn extruder x on, extruder x motor rotate y steps, and so on.
