Under the pretext to tell to Thingiverse people about pp3dp and their faulty Mini printer.Up printer NOW IT´S DOWN.I received a mini Up printer from pp3dp on 07 November 2012 and I have had a lot of problem with it. The mini came with an unlevelled platform up to 1,7mm and lacks of any levelling mechanism. I sent them a lot of mails but Pp3dp people are joking with me and I feel cheated. I contacted with his manager Joseph Guo that at first seems to be willing to help, but finally hi does the same, never respond directly to my questions but tergiversate them. They repeated all the time to put some paper here and there to adjust the platform and advised me over and over to use the beta software to level the platform, but it does not work in my computer and make things even worse. My previous comments on their blog have disappeared and probably my last one will even not be published at all. They offered to me to send the printer back but I will lose the shipping and the taxes I paid. That is no fair and It’s not just money. I want to get some justice. They sell printer as OUT OF THE BOX that it’s very far to be true. After I spent my entire holiday time modifying the platform, today, Sunday 25 November 2012, I finally manage to modify the printer adding a levelling platform mechanism, but the printer vibrates a lot and still I have not been able to print something decent. Also any time I initialize the mini it lost his Z zero point and I have to set it again. The mini has been so cheaply made that due to the weak clips it would not last too long. My Mini came with one clip broken and anther broken up when I take off the platform.Delta system knows that the mini has a lot of problems but still today they are commercializing it anyway. I cannot understand how there are there people making positive review of the up mini printer. Anyway, I KNOW that there are a lot of people that have had the same issue than me. I will start a campaign on the Web to inform people about the way delta Micro System is cheating people. I really hope no one will fall anymore into being cheated by Delta Microsystem.I will update this post. mixart
