Thanks for your responses guys !Got it working, though I'm not sure how..... which bugs me. I took printhead apart and put it back together to check all everything and also so I know how to do it, Still got the error. Switched to the secondary temp sensor, still got the error. Unscrewed the wires and put them back in, still got the error. Finally I took all the loom off the the wires that run to the print head along the bowden tube and rewrapped them, didn't get the error anymore.
I'm sure theres a messed up wire somewhere. I need to take apart the wire loom and better inspect everything. I'll find and fix the problem. In the meantime, I need this machine to make money for me so I'll just keep running it unless the problem resurfaces and forces me to fix it. I wish I would have bought the kit and put it together myself, that way I know how everything was put together. I may be in the market for another printer and if so, I'll probably buy the kit. Is there a place in the US where I can easily buy replacement parts for my Ultimaker?
