Newbie
Received the printer last week and assembled it on Saturday with just one issue. The filament sensor was plugged into the wrong pins. Image in the instruction book looked different than the instructions. Once changed over it ran perfect. Very important to wipe down the spring steel bed with alcohol very good before printing. Had a slight issue with filament not sticking due to this but other than that it's a great printer and the support here is terrific.

Did you grease the bearings before assembly?
And - keeping the bed clean is the hardest lesson new owners face:
Water wash: as needed
Handle the bed only by the edges.
Wash the bed in hot water, use a fresh paper towel as a wash cloth, with a few drops of plain dish soap (Dawn, unscented, no antoi-bacterial, etc.). Rinse well in hot water - if you have very soft water, rince a bit longer.
Dry the bed with a fresh paper towel.
Handle the bed only by the edges.
Place bed on printer.
Alcohol rinse: every few prints
Once in a while, an alcohol rise is helpful.
Pour a 5 cm puddle of 91%+ alcohol in the middle of the bed, use a fresh paper towel to scrub the bed. Wipe up all the alcohol.
Streak test: when contamination is suspected and after a wash
With a fresh piece of paper towel, and very clean fingers, dampen the towel with 91%+ alcohol, and wipe the bed side to side moving back to front, like you're painting it with alcohol. The alcohol should be thin enough on the towel it quickly evaporates. If you see any streaks, the bed is dirty and needs a wash.
Acetone wash: infrequent
Pour a 2 cm puddle of acetone on the bed, scrub it around with a fresh paper towel. It will evaporate fast as you clean. This step removes PEI oxides that form over time and with heat, and improves PLA adhesion to a like new state.
