Well this thing printed out one thing, and then I was unable to get it to work again. I let it go when I went to sleep, and noticed it started "printing" after about an hour and a half of sitting there. When I checked on it, there was no filament coming out. I turned it off and opened a PayPal dispute. I'm done with this junk. I can deal with mechanical stuff, but I can't do anything about firmware malfunctions. I'm just going to get the wood one. At least then I'll be able to find some support for it online. They kept trying to tell me the machine was not used, but that's laughable. Most likely they're playing word games. Sure the machine was probably never used as it is, but they built it with old used parts. Their excuse was that they had to put it together in a hurry, and that is the reason for these problems, not because it's used. I don't think that is really helping their case. They also told me they sold a total of 20 of these world-wide. Good luck finding one of those people.
