I bought this new, never got it to work. I could not get movement in the z-axis (vertical). Being brand new to 3d printing, I eventually gave up and bought something else (a Prusa Mini which I am also selling: https://boulder.craigslist.org/for/d/lafayette-prusa-mini-3d-printer/7930475426.html)
so this is basically a brand new Ender 3 Pro that needs someone with more experience than me to set it up.
