Used this 3d printer for about a month and decided it wasn't for me. I have unscrewed the standing side arms so it would ship flat. You will need to rescrew them into place and then there are several wire connectors that need to be plugged back in. Once everything is set up you should be able to spot where the connectors plug in they will only each to the correct plug connection. If you need help installing it go to monoprices website and download the instruction and software needed. If you can't find them YouTube has many tutorials on this printer. Manual and quick setup guide are included. PLEASE KEEP IN MIND SOME ASSEMBLY REQUIRED BEFORE PURCHASING THE UNIT.
