Foam XL hot wire cutter

spent a while looking into other rail options. I spoke to the guys at hepco however even there basic utili track is going to be more than genuine hiwin so that's out!

I think its going to be between plastic rollers direct on the extrusion or making some sort of v wheel of bearing setup that runs on steel.

I have seen a few options for this there is one were they are using angle steel bolted top and bottom to which the bearings run on which would probably give the most stiffness if I were to want to run it as 4 axis (sorry pic is a little small)

other wise I think I will maybe try and make my own plastic wheels ether by turning them on the late from something or perhaps 3d printing them maybe ?
