[QUESTION] Print quality in Overhangs #30

Closed Astrofreak85 closed 4 years ago

Astrofreak85 commented 4 years ago

With your profiles, when I reduce the max extrusion to 50mm/s I get good results, else my extruder sometimes skipped. But I have a problem with overhangs, like the front of Benchy. The layers thee alway curl ob while being printed. When I slice Benchy with Cura, and stock settings it looks good... What is causing the problem?

Need more information, such as: Is ender stock or modded? Filament used Temperature used printer profile + print used

Astrofreak85 commented 4 years ago

Ender 3 pro Not modded, just Metal Extruder an other cooling. Filament, PLA from "Das Filament" 210°C Profile: yours Ender 3 stock, Print speed is yours, not change for the print above

currently I am putting a print with same speed settings as used in Cura

When I compare Cura and Prusa print after the main deck of benchy is ready, it seems prusa uses much thicker walls...

The additional fill between the two outher perimeters seems to corelate with number of upper an lower layers in PrusaSlicer, at least changing this has an effect here, wenn i reduce upper and lower to 3 ist gone, and the print looks better, but still not perfect strange how different the slicers behave... maybe this has nothing to do with your profiles at all...

Diferent software have different planers and ways of print, it look like a overhang problem. You can try reduce overhang speed (bridge) and increase cooling fan speed on those cases which for PLA is always 100%. Also make sure you use latest prusaslicer + my profiles You can try set every setting equal to CURA and see if problem stays or not. I printed a bench two days ago with PLA and i don't have that problem, i'm using 0.65mm lines and 0.6mm nozzle which is worst for overhangs (more mass)
