I built his printer about a year ago and this thing is a beast. My only complaint is that either my lcd or ramps bord is faulty because any time I try to tweak settings mid print the screen displays random characters. I’m sure if anyone else orders one , it will work just fine. I cannot reccoment old this 3D printer enough. 8x8x8 inches,heated bed, 50 micron layer height and its easily upgradable. What more would you need.
