Have you ever used or built a 3D printer before? As a first project a 1m x 1m machine is extremely ambitious. Dual use as a laser cutter adds another level of complication.

The corexy mechanism is kept square by the belt tension. Even if you fix the X axis guide rail to the Y axis bearings at a rigid 90 degrees, the X axis rail(s) will flex.

It sounds like you're asking if an X axis guide rail is even necessary. Yes, it is. The extruder carriage has mass and has cables and filament going to it. Without a guide rail of some sort it will flop around on the belts. The X axis guide rail is there to stabilize the extruder carriage and make sure it moves only as commanded.

I don't understand the question. What do you mean by "floating?" All four end-points of the belts are fixed to the carriage so I cannot see where "floating" might come in. Well, unless the carriage is made of TPU!
