Hello! I'm working on a project at University of Coimbra and I don't know how to build a Extruder function on my project. I have already seen in Robodk API how they try to build it for post processing, however It doesn't seems logic for me. My first idea is to create a simulation of the 3D printing and then implement it in the "real world", but the program is always calling a extrusion program that I have no idea how to build it. I'm new at this subject and I'm learning on my own, so I need your help if possible.
