Im pretty sure the warranty is already up because the machine has been boxed up in my friends garage for about a year. She got it for her kid and didn't realize how complicated it was. Later on today I'm going to hook the board up to my oscilloscope and see what the z pins sets are doing. After that I'll probably assume the board is shot and just tell her she most likely needs a new one. At that point I'll have no problem removing the heatsink to see whats under it. What I'll do is put her machine off to the side and build my printers first. See how different my machines are to hers. This way if they are very similar i'll have her buy the newer board.
