Interesting 3D printer design.

Using 3 linear rails to mount the bed. I suppose each linear carriage is one “corner”/point and all three of them to define a plane without overconstraining the buildplate but you keep all of the rigidity of the linear rails.

The issue I see is that the three linear rails in one plane are overconstrained so it is still is a pain to setup (especially on an ender 3 like frame construction).

What is the reasoning for using two motors instead of one powerful in the middle?
