Hi, I have this hotend since 3 weeks. I successfully printed about 35 hours without any problem. Suddenly extrusion stopped after 3 hours in a 4 hour print. The problem was the thermistor not functioning any more like it should alltough I only found out this was the problem after one of the thermistor wires snapped just below the metal piece that connects the thermistor wire with wire going to the PCB. Once I removed the 2 metal pieces and twisted the wires together covering with kapton tape the issue was fixed. But now it seesm the filament is jamming somewhere. Before I have cleaned the nozzle and occasionally a little bit gets extruded so the nozzle does not seem the problem. My filament has 2 big heaps out of it because of the hobbed bolt. What could be the problem?
