I am new to this -but here is a bit I have seen
What printer do you have?
Print coming looses from the bed, assuming the printer is otherwise set correctly - try cleaning the bed real well, Lulzbot recommends a 10% I think it is Isopropyl alcohol and water mix in the manual. If cleaning with a wet rag does not work, get some 2,000 & 3,000 grit wet or dry sanding pad and a small sanding block (or make your own) and clean per Lulzbot instructions. i.e. with very wet pad and block sand the whole print surface starting with 2000 grit - you should see some milky color, the surface will change to a mat finish, when all mat finish switch to 3000 grit - -I am always a bit afraid of getting carried away so a bit cautious - also if you leave the finish at 2000 you might have trouble getting the print off.
The first layer might be the height set wrong, try cleaning the nozel and the 4 washers on the corner and also leveling the X axis in case things are not square
And if all else fails call tech Support, nice folks
