Thank you ! Last time i assembled a printer was some years ago. First time i see a bowden extruder..
Yes, seller confirmed 0.4mm nozzle.
And i actually had to increase the 89 because extrusion of 200mm only lead to 188mm :-/
I guess it is something mechanical. The Extruder lever moves up and down when the gear-wheel rotates.
And the clicking noise does not come from the filament slipping back but the gear-wheel is pushed back :-(
Tried with less tension in the spring (that pushes the lever and increases the pressure onto the filament) and it seems to reduce the slipping of the gear-wheel.
Uploaded a short video: [youtu.be]
In the very beginning you can see (and hear) the gear-wheel clicking/slipping back three times :-/
Ideas welcome :-)
P.S. first i could not load the hot hotend with the filament. Had to unscrew the nozzle and push the filament by hand (pressing the lever on the extruder) by hand through the hotend. Then a 3cm long PTFE tube appeared and i manually inserted the 1.75mm PLA filament into it. Then i could print. Later i extruded backwards to remove the filament and then forward extruding worked. So i guess this little PTFE tube is okay now.
