i finally got my printrbot plus 2.1 to start printing Monday night and all the prints on the z axis are being stretch when I print them they aren't like that in cura I figured out that my z axis rods are different then the ones they are said to be in cura so it's moving it to much but I don't know how to change it so it's for my z axis rods. Does any body know how to change it and to what?
