Expanding to 1800mm. What parts do I need

I’ve searched but cant find a set parts list for upgrading my xcarve to 750 x 1800mm. Does anyone have such list?

I’m also interested in this. Aiming for a 1000×1800mm myself with screw-drive and faster motors to make up for the speed loss of wormgears. I’ll probably also have steel rails machined locally after buying an aluminum set. As I haven’t built a basic one I do not know much about the part names or what half of it looks like, I just know what capabilities I’m aiming for.
