if you are printing this with pla you will want to use supports and a brim on the 2nd plate the first and 3rd will be fine without them unless you have bad with the second plate I would also add glue to your build plate if you have bad bed adhesion all plates are made to fit within a 220x220 build area oh and on plate 3 all the cams go on in order and all I can say is good luck the rest of the assembly is pretty straight forward. when putting followers on make sure the long side is facing out or it will not work
