    Recently I discovered my printer had a cracked part so I 3d printed a new part Robo designed. I popped it in and fit just fine. I ran a few tests before printing and here they are.

    1: I heated up the nozzle and through the motor options extruded filament- worked just fine
    2: I ran the fine z tunning wizard- it started clicking and not extruding
    3: I ran a test print- the same thing as above happened

    Does anyone have any suggestions? Thanks in advance!

    Sounds like your Z offset is too close to the bed.
    If that happens it can create too much pressure for the extruder to push out plastic.

    Rerun the Z offset wizard and fine tuning wizards

    In addition to rechecking the nozzle height:

    The difference might be the speed of printing vs the temperature of the extruder. As was pointed out in another thread, you are pushing a 1.75 mm filament through a 0.4 mm opening. If the temperature is not high enough for the speed which the print is going at, then back pressure can build which could cause the clicking (slippage) at the extruder.
    Try raising the printing temperature by a few degrees to help liquefy the filament.

    I tried both and it works :)

    That was a quick fix thanks!
