I've been trying to print my final Christmas kit card and it's not going so well. It was an 11 hour print and it failed at 9.5 hours. I think one of the walls was too thin and it collapsed. So I increased the size about 20 percent to beef everything up a bit which made it into a 14 hour print. It failed again at about the 12 hour mark. Some error about the print nozzle temperature being abnormal. I have followed all the troubleshooting and repair steps a dozen times and nothing is having any effect at all. I have ordered a new complete print head and it's going to take a week to get here. I also opened a support ticket to see what they can do to help me. I've seen this problem on a few different posts and there seems to be no consensus on what the actual problem is or how to fix it. It seems different things have worked for different people but in some cases it seems that nothing works. I'm pretty bummed out.
