Hi Folks,

 

I have an MK3S with a E3D hardened steel nozzle. 

 

It seems my Nozzle is a few mm too low and blocking the retraction mechanism.

 

You can see from this photo the crease in the foil - this is the ridge that is catching on the nozzle:

Here is a video of a manual x axis jog. You can see the pinda catching, the assertion/retraction arm getting nudged by it downward then the nozzle catches and eventually pushes against the mechanisms assertion from the other direction.

Tried both 2 and 3 springs, on single spring during the video. Pushing the retraction mech as the extruder body would manually - seems healthy.

It might be worth noting that the force of nozzle catching and the extruder body push simultaneously, sometimes causes the flicker's linkage to invert. This is the case in the photo and is fixed manually.
