Better Quality 3D Prints Using MAGIC NUMBERS

The stepper motor(s) that control your Z axis (height) has a magic number. Figuring out that magic number and specifying a layer height that’s a multiple of this magic number will make your prints a lot more uniform.

If your Z stepper motor magic number is 0.04 mm and you print 0.1mm layers (a default on most slicers), you’ll get banding and layer artifacts that will disappear if you use 0.08 or 0.12 mm layer heights.

Chuck explains all this and shows you how you can calculate the magic number for your 3D printer.
