The extruder clicking is more than often the sign of a clog. A clicking sound would be a partial clog, a thump would be a full clog.
9/10 times, this is due to improper settings. Most people have support settings travel faster than normal. If the material you are working with is PLA or TPU, for example, the material is being thrust into the nozzle without proper heating, is not melted completely, and upon finish, the "normal" flow attempts to break the clog.
Do as Carl says. Inspect the hotend and recheck your temp/speed settings.
