    CTC Makerbot Clone Extruder seems to be making a rhythmic clicking noise

    Had the printer for about a month with fairly regular use. I'm guessing its the gear that pushes the plastic through to the hot end that's making the noise, but I'm not sure if it was a setting I changed or what. Any help would be appreciated.

    It's the extruder slipping.
    Basically you're either trying to print too fast or too cool.
    It can't push the filament through the extruder fast enough and it clicks.

    I would imagine the gear is clogged up with filament dust and that the nozzle needs a clear out, along with possibly a new PTFE liner.

    I would also change the extruder drive to a sprung type, as they don't get clogged as easily.
