I will look into this. Thank you, I have had to replace my PTFE/nozzle due to clogging issues of the PTFE tube but I thought that was because something with the Z-Axis (being too close at some point and stopping the filament from coming out) or something akin to that. I’ll be honest I don’t know a whole lot about the inner workings of these machines, but from that image it doesn’t look like anything I’ve come across when I’ve had to dismantle the extruder / nozzle assembly to replace the PTFE tube / clean out the nozzle.

Will look into this further when I’m home tonight.
