I found a similar thing as Mark Hale to be true. The screws on the stepper/motor assembly on the back also need to just be snug (not overtightened). I was having lots of underextrusion and the motor was skipping all the time, even just manually feeding filament through from the maintenance menu. No clogs, teflon coupler was not deformed, bowden tube was fine, could not figure out why the motor could not push hard enough to extrude.
At the prompting of an Ultimaker support rep, I loosened all 4 screws on the head (the tall thumb screws) and the 4 hex wrench screws on the stepper/motor assembly on the back and retightened them only until they were just snug and no further. After adjusting the screws on the stepper motor/assembly, the clicking stopped and I have been printing fine ever since!
