UM2ext Kanten nicht schön

Recommended Posts

Mein UM2 ext. druckt seit einiger Zeit die unschöne Kanten :

Eckiger Testkörper 15x15mm  https://www.dropbox.com/s/990f8knwwg6qwyo/1.jpg?dl=0

Runder Testkörper d=12mm https://www.dropbox.com/s/fh55iqqo31pk5z7/2.jpg?dl=0

Sieht so aus als wären die einzelnen Lagen leicht versetzt ?

0.4mm Düse - Olsen Block - Temp 210 -220° - Druckgeschwindigkeit 60-70mms -

Ich habe diverse Slicer Einstellungen (Cura 3.0.3) getestet.

Der Drucker hat ca. 2000h gedruckt der PTFE Kuppler wurde bereits 2x getauscht (der jetzige ist recht neu).

Hat jemand einen Idee-Ansatz ??


Firmware Thinkercad 17.10.1.

Tinkergnome 17.10.1 - PID schaue ich mir an.

Die Z-Welle habe ich gereingt.

Habe jetzt gerade mal den PTFE Kuppler getauscht (ob wohl noch gar nicht so alt).

Mache gerade einen Testdruck.
