For the second time I've tried to print something, my printer just stops extruding about 75%-90% through the print. I've replaced the nozzle, feeder gear, and heater block. I tried to print something over night, woke up to part of a print. What it did print was fine. I didn't power cycle the printer after it was done and the printer is not extruding. Even in a test of just moving filament through, nothing is coming out. It's to correct temp so no problem there, but the motor for the filament appears to be making a strange click noise. I'm pretty sure if I power cycle it would start working again. Is the motor going out or is this a printer firmware issue?
