Over extrusion before print starts

Recommended Posts

Posted · Over extrusion before print starts


I have a problem with extrusion.

Everytime before the printhead starts extruding filament for a new layer, the used printhead extrudes extra filament. You see the extra filament in the photos.


First I tried to change the retraction and the temperature (less) but I gues it's not the problem, because the print result of the actual part isn't that bad.

Than I tried it with an ooze shield, but the extrusion didn't stop with the ooze shield, so it's useless.

I also tried to print the part with the slicer software simplify3d, but the result is also really bad (see picture).


This is my setup:

Ultimaker S5

Printcore AA 0.4 Tough PLA (from Ultimaker), 

Printcore BB 0.4 Brakeaway (from Ultimaker)

Printing temperature: 225°C

Print Speed: 70 mm/s


Do you have any ideas or tips for a successful print?
