Flow Math: Slicer extrusion logic explained.

Описание: This is a more technical kind of theory based vid so I though I'd try to colour code the thumbnail. Red = theory, yellow = more mainstream tips and help...if that makes sense. We'll see how that works out, no doubt badly.

Cura and Prusaslicer don't work the same. No, I mean they really don't work the same. Watch and see how.

Included in this video is how the math(s) behind the scenes is working with regards to extrusion in the GCODE and how your settings for layer height and line width change this, and what nozzle size to use with which heights, and so on.

Also includes, for some inexplicable reason, play doh.
