After a ton of reading on here and other sites after I got mine, I seem to have gotten the short stick. Mine didn't print for spit out of the box. After all the printable upgrades were done it was like a completely different machine. Though, I still have problems with circles not being round. I'm currently waiting on aluminum gears to come in from China. They should be here some time between next week and August (Hooray for international shipping!) I'm really hoping the gears make the difference, because the only other option I have is a dying motor. I'll find out later, because if I'm going to be taking the whole thing apart, I'll just make a day of it.
