Why is it conventional to set line width > nozzle diameter?

I recently became curious about the Line Width setting in Cura and why one might change it if they aren't using different size nozzle. Since I've gotten my Ender 3, I've always kept the line width equal to my nozzle size (0.4 mm). I've looked around…

Why do some models appear broken in slicing software?

In my slicing software (Slic3r) some of the vertices/walls of my model seem to have disappeared, so that the inside of the model - which should be solid - is visible, while the surface appears as a thin shell. Why does this happen? Is it still safe…

slic3r: Can I vary the infill percentage for different heights of my model?

How can I vary the infill percentage for different layer heights of my model? Context: The bottom part of my model needs about 20% infill. The geometry of the top part of the model (mostly cones of various sizes) prints well with 0% infill and is…

How can I create PNG image files from STL files?

I need to add some simple image renders of STL files to a document. I currently open the STL files in Preview or one of the slicers and grab a screen shot. Is there an easier or automatic way to generate PNG images from STL files on a Mac?

Turning off heatbed for the last few layers. Good idea or not?

My heatbed won't let go off the prints until it considerably cools down. The cooling process takes decent amount of time. I was considering putting the M140 S0 (sets heatbed temp to 0) somewhere near the end of the printing process, so that when the…

Skipping Y-steps, only when using Ultimaker Cura

In order to find out why my printer sometimes skips Y-steps (always in the same direction) only in Ultimaker Cura, I am digging into the G-code to understand the problem better. However, thousands of lines of G-code are hard to analyze. I am using…
