how line width and nozzle size comes into consideration

hey,

im trying to understand how does the engine calculates a path to print, using the nozzel size.

for example, if the printer head needs to print 3 lines in a narrow space to create the desired wall thickness, where or how does it decide to print 3 lines next to each other?

i guess if i know the thickness and the nozzel size i can calculate it, but where can i see it, in order to add my own calculations?

This is a fairly simple question that does not have a very simple answer. Here's a start: https://github.com/Ultimaker/CuraEngine/blob/5.0/src/FffPolygonGenerator.h

yes i've seen this file and read it before, but hard to undestand where is the actual calculation,

for example- does it slice walls and decides that it needs x parallel lines for it, and than based on the nozzle decides how many really should the printer head do, or what?

id like to write wy own way to calculate the needed path to print.

I can't answer your question, but out of curiosity: is there a specific reason why you would write your own algorithms? Instead of just changing existing parameters to suit your needs? Probably 99% of the work is already done by the developers, and you only need to change minor settings?

 

Unless it would be for a self-study project to gain more understanding, or for new scientific projects with other materials or equipment, or so, like printing in biomaterials or concrete. That would be very valid reasons. I don't want to invalidate it, I am just curious.
