3D printing forums

I followed the blog of burdickjp himself and that worked for me  

Hallo zusammen,   hab den Dom gestern noch 2x gedruckt. Bei Dach 3 hatte ich bei einem der Drucke kleine Löcher drin, aber überschaubar. Ich denke generell mehr Schräge ----> weniger Gefahr für Löcher. Vielleicht kann man nur die kleinen Dächer auf der 3er Dachseite etwas schräger machen?   beste Grüße und ein schönes Wochenende Euch, Ben

When you don't print too much spools nothing happens, but if you plan to print it more often, then you should think about an upgrade to the Bondtech feeders. They have hardened gears.

The bottom needs support...but that is supplied by the build plate.   the 3D design is represented by a mesh of infinitely thin triangles that describe the surface of object. If you zoom into the mesh of the sphere, you will get to a point where rect triangle is a flat surface, or “face”. Associated with that triangle is a “normal” vector that is perpendicular to the face. But does that normal point outward or inward? Properly described (by convention) the normals point outward.   Cura uses the normals for its display (the slicer doesn’t care and uses a different mechanism). If the face normals point downward by a steep angle, it colors red as a hint. If the sphere normals point inward, the ones on the top faces are pointing down...thus why Cura colors it red.

Thx, I'll try reading it through.
