Assuming everything is calibrated perfectly and when I set the Extrusion Width to a value, THAT is what is actually printed...what are the reasons for going with one width over another? For example, my nozzle is 0.40mm, but the "auto" width is 0.48mm. A lot of people here suggest always going at least a little higher than the nozzle diameter, and I've been printing at around 0.45mm.
I guess what I'm not clear on is why I might want to go closer to 0.40 vs higher towards the 0.48 setting. Other than just having thicker walls for strength does it affect surface detail and quality? From what I understand S3D alters the space between your paths to accommodate the set width (assuming you have calibrated extrusion mult correctly) so their shouldn't be any gaps no matter what the width value. Is it also safe to guess that with smaller layer heights you want to avoid too high of a width value. Seems like I heard somewhere that 1.4/1.0 width/height ratio is ideal.
Any more info is appreciated.
Thanks,

Re: Extrusion Width - Recommendations?
mitch, the width generally does want to be a little over your nozzle size but in the end the width is set depending on the model your printing. say you have a box and in the model the walls are 1.1mm thick. with this you would end up with a single perimeter on the inner and outer surface of the wall and be left with a gap in the middle. this is no good so you would want to set your width to .55mm. this will make for a solid wall with no gap. for the most part you can leave it on auto as default then alter the width per model as needed. a .4 nozzle generally can be print from .4-.65mm. the upper # really depends on the nozzle though and how big the flat is on the tip of it.
Re: Extrusion Width - Recommendations?
Great info!
In the case of the box with a 1.1mm thickness and a 4mm nozzle;
If the nozzle setting is left on auto will it print those shells at 5.5?
Trying to figure out what "auto" actually does and what it's based on.
Thanks for any help clarifying this.
Looks like you had answered that in another thread.... It makes the width 120%

Re: Extrusion Width - Recommendations?
yes there is nothing intelligent going with the auto setting. no on the fly automatic adjusting. atleast none that i have ever seen. it just sets to 120% and thats it
