My Bro got one for his birthday. It was a kit so it took us 2 days to put it together.
Step 1 – put it together
this takes well over 4 hours
Step 2- level it
We initially skipped this step (not a good idea)
I also found out that there is some firmware you can update and have the printer use some measurements to level the bed using a calculated plane with a Gcode before you print.
Step 3- Software
It was a bit of a pain in the ass to get the drivers working and it is still kind of confusing to work with. (open and connect with Repetier, print with cura)
Step 4- Print
