3d prints keep shifting left and right. I put pillow blocks on the z axis rods to stop the bed moving side to side and that made it a bit better but the bed is rock solid now and there is still shifting. the last picture is showing that there is shifts at similar locations on the 3 prints. the layer shifting also doesn’t seem to affect short prints as much as tall ones. does anyone know how to fix this?

Umm, what printer do you have?

Ctc dual/bizer (lots of names for it). It is a makerbot clone.
