Extruder Noise; Click when retracting  

Extruder Noise; Click when retracting

Hello,

Since one week i'm the lucky owner of a Prusa Mk3 kit version. Assembly went fine and no problems untill now ( and still really haven't got one ).

Recently i start noticing a small but present "click" when the printer is retracting ( Z-hop or no Z-hop ). I'm not directly having a problem with a clicking sound but i cant seem to stop thinking there is something wrong with the extruder. The sound is definitely coming for the extruder but i cant seem to pinpoint the exact cause and fix. Seems something is smashing into each other.

So far i've checked:

- Idler Tension; tryed loose, and tightend and everything in between
- Made sure its not the nozzle touching something ( Print or bed )
- Checked for Clogs; None, also did a Cold pull no dirt or w/e
- Tryed other Material PLA and PETG both the same
- Tryed playing with retraction settings, only fix seems No retraction 🙄
- Checked for loose Nuts
- Checked Extruder gear alignment
- Tryed increasing and lowering Extrusion multiplier
- 'Ruled out' for faulty slic3r settings, since the prusa Gcodes also have the clicking

So far nothing helped. Is something faulty? or is this sound 'normal' ( doesn't seem normal to me. )

Please help 🙂
