Clicking Extruder on Lower Temps

Hi Everyone, recently i've just finished my Smartrap Build, but when i tested it the other day, it seems that the extruder is making clicking noise several times at some point, and the extruder cannot push the filament through,and then when i change the hotend temperature to 230 deg, the clicking noise is gone and the filament is pushed through smoothly, but when i print something, the result is somewhat not very good, and has blob in it, anyone has idea of what might be causing this clicking noise, and how do i improve my printing quality? i've tried to turn down the temps to about 210 deg, and lower the feedrate in the repetier settings, the extruder still make clicking sound several times, BTW I'm Using PLA, Thanks

Make sure you have your Vref adjusted properly (via the potentiometers on your board). It sounds like your extruder motor isnt getting enough current.

You should probably also tune your PID settings and cross check the temp readings from your hotend thermistor with an IR temperature reader.
