Both Tekma3D and New Matter both came out with printers that use crossed splines to drive the x and y of their printers. They both are in the process of trying to acquire a patent on the technology. Being the open source hippie that I am, here is a system that is functionally the same but should give a wide berth to the patents.
To be clear, I don't think this kind of system is very good. I think it is fun to watch.
If the system has opposing racks as shown, one screw should be left handed and the other should be right handed. If all the racks face the same way, like the MOD-T, then you can use two left handed screws. The system is driven just like a CoreXY system.
