What is Zits, or, Blobs?
While 3D printing a model, the extruder must constantly stop and start extruding as it moves to different portions of the build platform.
Blobs are these visible lines, or separations you see on the 3D printed models.
Have a look at this example.
If you start to notice small defects on the surface of your print. The best way to diagnose what is causing them is to watch closely as each layer of your part is printed.
its possible your retraction settings need to be adjusted.
Adjust your Retraction speed until you get a smooth surface.
Thanks for watching
