Hi all - I have a Flashforge Creator 3 which has been running great for months now. Just installed a 6mm hardened nozzle and ran into problems. My right heater is now registering 1025 C when viewed on the STATUS screen and will not heat up. Possibly I shorted something out while disassembling/reassembling the nozzle assembly? I then replaced the thermocouple and swapped out the Right Extruder Circuit Transfer Board with a new spare. No luck. However, still able to print with the left print head. Before going forward replacing the heater and other component attempting to eliminate the problem, I wanted to check with those more knowledgeable than me. Any suggestions?
