Hi! I Love my ReprapGuru. I do have an issue where one of my z threaded rods were bent on arrival. I've been making due for now but it causes some wobble effects, especially on larger prints. I'm going to be switching to a lead screw z axis, however I'm having a hard time finding printed parts that work with the Reprapguru. Either the lead screw is too far from the guide rod...or won't fitby pantaros - Prusa i3 and variants
