Hi folks, just stumbled across a vid of somebody testing ripple and backlash with different kinds of rods for the gantry at the same accelerations. Reducing moving mass on the gantry should lead to more precision and less backlash. Has anyone of you tried this on a Bigbox? How strong would a carbon rod need to be for this to be a good thing? How about abrasion done to it by the bearings, would it work with IGUS self lubricating bushings?
