CNC Hotwire 4 axis foam cutter

[Skipsoaring]

I've been playing with fusion360 and have come up with a bit of a design.
I've designed it so that when I'm not cutting cores I can utilise a flat surface for other projects so have gone a bit over the top with regards to the structure.



The idea is that the runners are interchangeable on the supported rails to enable some flexibility in the length of the cutting wire and it will be tensioned with a weight over a pulley.
The vertical axis will have a little bit of lateral force applied to them as the bases move independently. To deal with this, I am aiming to use hiwin rails for the vertical block.
There is hardly any force required to pass the wire through the foam, so I am planning on running belts and pulleys to control the axes (as per printer).
My drawing isn't very good and doesn't allow me to change and modify things (still learning CAD on the fly) but I am also aiming to do some epoxy levelling to the frame before mounting the rails and plates.
The way it is drawn at the moment gives a max effective cutting area of 2100mm long x 550 wide x 170mm high.
Just looked at the clock and I am about to be late for work! Gotta go! Sorry if it's a bit disjointed (The post) hopefully you get a little bit of an idea about my project.
