As a first project, I would like to build a large (1m x 1m) plotter / laser cutter. The idea is to get familiar with all kind of topics before I begin my build of a 3D printer. Also, I have some actual use for this device.
Now to the coreXY mechanism: It seems to me that the belts keeps X and Y axis orthogonal (given that the pulleys are at the right place and firmly anchored).
My question: Is it correct that because of that the carriage could actually be "floating" between guides that prevent it from moving laterally, i.e. that I don't need a fixed 90° fixture to the lateral fixed guides? I understand that such a 90 degree fixture could bring additional dynamic stability, but couldn't it also lead to binding?
If that is true and not having a rigid 90° fixture does not have several practical disadvantages, this would make the design of this large thing much easier and the structure more lightweight.
