My 2.x is scaled up to 780mm X 430mm. This is already much larger than the standard 2.x. I wouldn't go larger than this for a makerslide based machine. Makerslide is straight, but not really that straight. While doing final leveling it was impossible to get dead level with my machinist level because of bow and twist in the material. I was able to get the alignment good enough to cut, but it needs periodic tweaking.
One advantage of a later size is if you want a higher power tube it fits no problem.
