Fine tuning a Cura Profile

[KC1SA 0]

I have a profile for my printer I got from a forum and for the most part I'm pleased with the results.  I run PLA only and have printed temperature towers to get the optimal temperature setting for my material.  My machine is a 3 extruder - 1 mixing hotend machine.

 

With the multitude of settings when setting up a Cura profile, is there a go to manual / book to reference to really know how each setting impacts the slice and print result?  Currently my profile works well  but it needs tweaking.  I do get stringing and some rough surfaces on vertical surface; some but not all.  The stringing and rough surfaces seem to be impacted by the direction the x-axis is moving;  stringing primarily happens when a right to left movement and rough surface seem to happen when a left to right movement.

 

I'm not looking for "the answer" but really wondering if there is a reference manual / workshop / video tutorial on the subject.  Most of the beginner / entry level videos are too fundamental and I think I'm more of an intermediate level user.

 

Many thanks in advance for the assistance.
