I heard mine clicking the other day and saw the feed motor send the filament into the side of the throat and not down it to the nozzle. My nozzle was unscrewed quite a bit and the throat did not extend up all the way to where the filament is fed.
I hadbthe same issue with the calibration. The official fix was to loosen - not remove - the three screws that hold the vertical axis. The whole thing then moves down a few mm, enough to bring it under the 185,then tighten again.
