Overhangs with fiber-filled filaments & Orca settings - am I missing something?
Hey guys,
I am having serious trouble printing overhangs with PA12-CF, but also PET-CF,... And I think I am just doing something wrong.
Basically, when printing inner/outer or inner/outer/inner, I always encounter this horrible sagging.
Additional info:
I am printing with enclosure, about 50°C
Increasing cooling, even to 100%, didn't help at all
I am printing overhangs slowly.
It happens regardless of temp. Mfr recommends 250-270°C, I tried all temps in this range.
I print with a silicon carbide nozzle, NextG Fiber hotend, Orbiter2.5 extruder.
Only the outermost perimeter is affected, always. The internal bridge and other perimeters (despite being overhangs) print perfectly fine and flat. It's always just the outermost perimeter. When printing, basically it starts to sag immediately after leaving the nozzle.
Are there any settings in Orca slicer I should toggle? Am I missing something? What am I doing wrong? 😕
