Well the wire never touches the foam when cutting, so there is NO pressure on the machine from that, the only thing you need is motors strong enough to move the weight of the machine.

Re: Building a new large CNC hotwire
It looks like the main challenge will be obtaining smooth motion and not having wobble in the large components.
While that might seem easy, it often is not quite that simple over large distances. I would look at what is done over in the wood cnc home built section in terms of frames. Most of those are actually not stiff enough for the intended task, so they are about right for your task.

Re: Building a new large CNC hotwire
Following. Starting to research building (or maybe buying) a foam cutter that could handle a 96"x48"x48" block of foam (the wire would need to be 98" long). Seems simple enough, X,Y on one side, Z,A on the other, hotwire stretched between.
Like building two 50"x50" machines facing each other. Looking at other threads it appears that most of the heaving lifting of programming has already been done.
