Comment on Linear rail mod on Anycubic Kobra 2

Industrial linear rails can cost more than the printer itself. They should be mounted on proper flat surface like tooling plate (aluminium extrusions are far from best option) with extra attention to mounting tolerances. Smooth rods and “wheels” are way more forgiving to any missalignement.

Well…there are knockoffs like hiwin on ebay, and they seem to work for many people even mounted on aluminium extrusions. I think you should get your frame as square as possible first and see can you stay on wheels motion system to avoid upgrading cost. If frame is not good enough for wheels I would be afraid of even more issues with rails (binding and simmilar). But keep in mind I have no experience with your printer or any kind of wheel system and I never did upgrade from wheels to rails or anything like that. Im just trying to help, but hopefully someone who did that kind of upgrade can provide better answers
