Hi,
I have a problem with the Slicer settings in S3D and I think I've already changed almost every parameter, but nothing worked.
When I'm printing, for example, the 20x20x20 calibration cube, I get blobs on the surface of the cube. These blobs are caused by the retraction of the extruder. I have changed the retraction distance, speed, acceleration and even the coast distance but the blobs are still there.
Now, I have sliced the calibration cube with Cura (v. 3.2). No special settings, almost the standard settings (even with retractions for every layer). And after the print was done, I had a nearly "perfect" cube with no blobs in my hand. So, it seems that it isn't a hardware problem, but which parameters are different? Has anybody a clue?
My setup:
Printer: Creality CR10
HotEnd: (original) E3D v6 Hotend
Filament: PLA
My settings:
Retraction Distance: 2.6mm - 3.0mm
Retraction Speed: 70 mm/s
Retraction Acceleration: 3000 mm/s²
XY printing speed: 60 mm/s
XY acceleration: 3000 mm/s²
I would be very happy to receive an answer!
