From the top review on Amazon:
Ok I just received this printer and so far it's amazing! However I've noticed some people on youtube or other places that shows them having a bit of trouble setting it up so if you're planning on getting this printer use the following steps to have an awesome experience.____________________________________________________
0.) Order a spool of Hatchbox 1.75mm Filament to either arrive before or at the same time as the printer. (The sample PLA included isn't enough for anything)
1.) The VERY first thing you do is use an X-acto knife to cut away the corners of masking tape covering the bed screws! LIKE I SAID THE VERY VERY FIRST THING!
2.) Use the provided Allen Key to lower the bed at each corner TWO full turns!
3.) Remove the tape from the hot end (NOT THE YELLOW TAPE AT THE NOZZLE) but the one that holds the hot end in place for shipping
4.) Plug in the power supply and turn it on
5.) Navigate to "Move>Home" and home the printer and guess what? The nozzle won't dig it's way into the print bed because what? YES we lowered the bed first!
6.) TURN THE PRINTER OFF!
7.)Now use a strip of regular typing paper and gradually start to raise each corner while checking the tension on the paper until you feel some resistance but not too much. In other words like a guitar we tune up not down!
8.) DO NOT UPDATE THE FIRMWARE UNLESS YOU NEED TO TO TROUBLESHOOT LATER ( In spite of what some gurus say on youtube)
9.) Take your SD card, load a test Gcode from Thingiverse (Print something you'll actually use like the New Dial for the MP select mini on thingiverse) it takes 26 minutes to print (NOT THE CAT! it takes too long!)
10.) After each print leave the filament in the nozzle and never try to pull it out once it cools because you'll break the hotend! To switch filament (Empty spool or different color) Preheat to 210 wait for it to reach that temp, extrude a little bit and then pull it out from up top)
I wish this info was put together in one place like this when I was reading reviews, It took me like 4 weeks to gather all the steps.
Now stop thinking about it and just order it!, a year ago you'd have to spend $500 to get a printer this good
And here's a good review of the printer.
