Hello! Thanks for taking the time to read about my problem! I don’t currently have access to the printer, but I know the problems I was facing and will have the printer again in about 24 hours.My school received a 3D printer three years ago. When it was first put together it worked flawlessly. Then it was left in a closet for a year and accumulated dust and debris. The people who had it before it came into my hands cleaned it and re-lubricated the the X and Y access. When it boots up it says “Heating Failure #4 my temperature reads are failing! Please check my connections.” The people who handed me the machine told me to ignore the issue. After figuring out the best settings, I made a few test prints and everything worked fine. Most projects had to be large because it was terrible with finer detail prints (mostly due to my lack of knowledge). Eventually, anytime that the active cooling fan was on, the temperature of the print head would slowly dwindle down until it reached a point that the printer would force stop. Looking online, I realized that the “Heating Failure #4 my temperature reads are failing! Please check my connections.” was more important than I was told. I haven’t printed anything since and wanted to know your opinions.At the time, I didn’t want to sink too money or time much into a printer that isn’t my own, so I didn’t attempt to resolve this issue sooner. Now, I have the support of the school and would like to know which steps I should take in order to fix the machine myself.Thank you! http://ift.tt/2aMPLvD
