Hello Steven,
Yah, I too know about the coffee thing...
And yes, the previous post mentioned settings are not specific to any slicer, printer or nozzle size.
ExtW, WoTr, #Loops, and Skin Thickness settings, apply more to your design intent, part geometry, and end-use application for the part.
All are critical to your design intent, printed part's quality, level of detail realized, overall strength, and in accordance to part's intended end-usage.
Note : HE Nozzle = Hot End Nozzle

Hello Jomo,
For me, I set my Extrusion Width, Skin Thickness, and the number of Loops to be based on several things :
1) Respecting the printed part's structural integrity.
2) Overall required level of detail in printed parts geometry, and intended end-usage.
3) The perimeter strength desired.
4) Any Wall Thickness that may not have room for proper infill, with set ExtW, IExtW, #Loops, and Skin Thickness. Inappropriate settings can instantly compromise the infill paths and quality of infill, or negate infill completely.
5) And if any post-process cleanup is needed, and I need additional perimeter material available for this.
Basically if you need to manually clean/file/sand/polish up the perimeters of the print, you want enough Loop/Skin perimeter material thickness as so you do not break through the perimeter Loops/Skin and penetrate the infill zone during post-process cleanup.
Quick Notes :
- Select an Extrusion Width that in respect for the parts geometry, part size, level of detail, any wall thickness, and the printed output precision required. A narrower ExtW/smaller WoTr which allows for superior fine details and precision in your printed parts. This is necessary for producing clean hi-res prints with fine details, sharp corners etc.
- Select and Add more Loops, and more Skin Thickness for strength as needed.
For most printed parts, my preferred perimeter wall thickness for printing is :
2-3 Loops, .5mm Skin Thickness with a ExtW of 1.3-1.8 WoTr.
