I believe that since you are going to be cutting foam, I will assume that you are speaking of a hot-wire foam cutter. I have read somewhere that you could "piggy-back" the motors (Left and Right X-axis, Left and right Y-axis) as long as you do not exceed the current rating of your driver boards and you do not want to make a tapered cut. Since you only have two drivers both the left and right cutting towers will make the same movements.
I hope this helps you out.
