It has been 10 months since I bought a Raise 3D N2 machine. I have struggled for 10 months to get the machine working. I even had to return the machine to get it repaired. It was returned to me with proof that it was working by having printed out a plastic frog with PLA. Yet, I could not get it to complete a single print. When I wanted to print out the same plastic frog in PLA, the machine closes down (this has occurred 5 times) It is an unusable machine. Techonology outlet will only refund me £1000 after having spent over £3595 £2479 of which was on the printer itself. With the advise from the very persuasive support tech to buy the additional technology outlet 3D printed addition to improve spool feeding for £250. I think this addition is a very unprofessional design - poor assembly instructions and poorly thought through with adjustment needed to inadequate dimension of support structures to prevent spools from being hindered as they rotate. Alternatively, what was sold to me was an incomplete piece of kit (more likely) The advice to buy the Simplify3D software may have also been and expensive mistake to follow. The actual Raise 3D machine seems to be an excellent piece of kit, and the manufacurers are good at supporting it but the Technology Outlet leaves much to be desired. Initially, I could not get the machine to work. So I tried to send it back immediately (within the first week) but they said there would be a 20% charge for returning. So I kept the machine and decided to work through all the problems after I returned from 2.5 months away. The technology support person had moved away by then - not a good sign! There was still support, however, ultimately I needed help from the manufacturers (good support from them). However, the extrusion nozzles kept on blocking. I replaced one of them and it blocked also. With manufacturer advice on how, I tried to remove it and it broke off inside the machine. The series of problems have wasted many many hours of time. I have never had such a problem with a machine ever. Perhaps, it was a dud machine. (Now I know it was a dud machine but the distributors just want turnover and once it is sold, you are stuffed!) So, the meaning of the terms and conditions state that the prerogative to refund is the managers decision. He flatly told me that they do not not do any refunds. That is what those terms mean to this company!
