Formfutura Flexifil, S3D versus Slic3rPE Stringing Wahnsinn
17. July 2018 16:42
ich probiere zurzeit Formfutura Flexifil aus. Habe meinen einen Extruder dafür etwas umgebaut und kann damit jetzt TPU und ähnliches drucken.
Heute habe ich zunächst einen Heattower gedruckt. Von Thingiverse hatte ich zuerst den gcode geladen, der laut Header wohl mit S3D erstellt wurde.
Das klappte zunächst auch gut, aber ich musste die Drucke sämtlichst abbrechen, da sie auf meiner Filaprint bei 60-110 Grad sofort gewarpt sind und spätestens nach dem 40igsten Layer abgefallen sind.
Ich habe dann die STL nochmals selbst mit einem breiten Brim gesliced (Slic3rPE) und die Temperaturwechsel wieder eingefügt.

Was ich nun bemerkt habe, der S3D gcode hat praktisch überhaupt kein Stringing produziert, während beim selbstgesliceten das Stringing fast so dick wie eine Bridge wird.
Hier erstmal das Foto, zwei abgebrochene Drucke, links S3D rechts Slic3rPE:


Vielleicht können die Experten mal einen Blick darauf werfen und einen Tip geben (selbst wenn der lautet S3D zu kaufen smileys with beer

Viele Grüße,

Gunnar.

Hier nochmal der gesamte Heattower, gerade fertig geworden. Das Stringing ist scheinbar fast temperaturunabhängig. Auch wüsste ich jetzt nicht, welche der Temperaturen nun die Beste ist.



Wäre toll, wenn wir das herausfinden könnten...

Hast du den Retract angepasst?
Meiner Erfahrung nach, braucht flexibles Filament deutlichst mehr Retract als steifes Filament.
Ganz schlimm wird es in einem Bowden. Bei meinem Hexa fahre ich Extrudr-TPU mit über 8mm Retract...normales Filament liegt irgendwo bei 4,5-4,7mm.
