kinda like a computer yeah, but if you plug in a cable backwards your printer makes a horrible noise as the head moves the wrong way and crashes into the assembly the first time you turn it on
i hated the assembly of my cheapo chinese 3d printer i think most of the ones from brands like anycubic come more assembled than that so the assembly is easier though
@handy333, If you have any Microcenter stores near you, goto 1 and they have a bunch of diff 3d printers on display and some will be printing even. But don't buy from there, order it online, will be cheaper.
