My Anet A6 suddenly stopped extruding enough filament after a period when there had been a lot of clicking from the stepper. I am reasonably sure the nozzle is not blocked and that the gear wheel on the stepper is correctly engaging with the filament, and I have tried it with two different control boards. I have measured the amount of filament extruded when I do a manual extrude and it is much less than it should be, so I suspect that the stepper is damaged. What is the correct replacement stepper motor for the extruder on this machine?
