Re: Extrusion blobs with S3D

Hello dkightley, So....to sort out zits......check whether the zits are at the beginning or end of an extrusion run. maybe you didn't read my first post completely, because then you would have read that it is a retraction problem. I posted three pictures and in one of them, you'll see the preview of...

Re: Extrusion blobs with S3D

Please excuse my late reply, but my printer had a more serious mistake this week. Since this is fixed now, I can turn back to the "blobb" topic. I've increased the number of perimerters to 3. The standard cube looks now better (not perfect) so I've dared myself on a bigger model. However, the blobbs...

Re: Extrusion blobs with S3D

Hey wirlybird, thank you for your response. Hm okay...I know what you mean with the negative restart, but isn't there any other solution? This would be more like a "dirty fixing", because if I would like to print a grid-model (e.g. klein bottle), then I'll have the problem that the printer extrude a...

Re: Extrusion blobs with S3D

Hi rrdavis, I get extrusion blobs on any of my models. And they are not random, they are always there where the retraction ends and the extraction goes further. Beleave me, my retraction settings are still perfect (e.g. no stringing) and the parameters in both programs are the same. The "Cura Cube" ...

Extrusion blobs with S3D

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 ch...
