/diy/ - Do It Yourself

I bought a Chinese Prusa clone and got it running, made some decent test cubes and a benchy so far. One issue I've had is that I get a regular "ridge" in the Y dimension, and I've figured out why, the Z axis threaded rods slightly shift around as the bar is raised, and the x axis carriage with the extruder on it tilts forward a fraction of a mm at a certain degree of the threaded rod. I figure this might be because the threaded rod is connected to the Z axis steppers with a rubber hose. I've got it on as tightly as it goes, but it hasn't really improved. Do you reckon I might see better accuracy if I replace the rubber hose with a solid bushing, like the Geeetech Prusa clones use?
