Yeah, that is a limitation for those people using really big stuff. Maybe this would appeal to the printer/laser crowd. In any case, it might help to simplify the Z a bit. As for the X-axis belt loops, I figured that could be an issue with wider machines – long belts = potential stretch. Again, maybe more suitable for smaller builds. My thought was to remove some of the weight/inertia from that axis, but I guess it really doesn’t matter. Just putting it out there.
