Fun and games

Well this Kickstarter has been a very interesting and, by and large rewarding experience for me. This is my first 3d printer and I enjoyed buliding it, although I did take my time as my electronics experience is limited.  I was quite relieved when everything worked when I turned the power on! I have been amazed by the quality of prints it is capable of producing but there are a few niggles and now a more serious problem. The niggles are firstly that if have been unable to resolve the adhesion issues without using a raft. I have tried adjusting the build plate temp, up and down, checked my geometry tweeked the z axis and given the plate a good clean but except if I print something small, right in the middle, it just will not stick without a raft. The second is that I still do not have the dual extruder working after the second servo failed during calibration. An oddity more than a niggle is that the print times given in Cura seem to be seriously underestimating the actual time taken.

The more serious problem came up today. The printer tripped the electrics. I have had a good look around it, there do not seem to be any loose wires or obvious shorts, everything that should move seems to be free to do so. When i tried to restart it there was a faint pop and the electrics tripped again. My suspicion is that it's the PSU. Anyone else had anything like this? So sadly I am currently printerless.
