One more piece of info: I scrapped the supplied build stickers (I had to squish so much to get it to stick that the print was pushing plastic around building the first couple of layers) and went with BuildTac adhesion stickers (I loved them with my older R1). Here is how I set it up, and I think it contributes to a good print.... I used the "z-offset" recommendations (brought up the platten until it just grabbed the sticky note paper (I could feel the tension but I could still move the paper....with a grip)..... then I hit the z offset button down (negative) three times. I tried 1, then 2 and finally was most happy with three clicks. I still get just enough "squish" for a good bond, but the parts just pops off when I am done. They only offer a 6.6 x 6.5!option at this point, so I had to cut it down 1 inch each way, but you'll get a better looking bottom than what is supplied.
