I know several have addressed this or a similar topic in the past but I can’t find anyone’s actual solutions for the issue. I have an X1E that gets daily use in my Library’s Makerspace. I had a piece of filament get stuck and followed all of the steps to clear out the piece - was stuck in the extruder. Upon putting the machine back together, the hotend now reads at a constant temperature of 255 degrees. I’ve replaced the hotend and the extruder connection board thinking I may have damaged a connection when plugging everything back in. This didn’t solve the problem. I’ve factory reset the machine and done all the updates to the machine’s firmware.
My next thought is to replace the TH board but I wanted to see if anyone had found an actual reason the machines are doing this before I replace the entire thing piece by piece. Can anyone offer any solutions that have worked for them?
