Why changing Line Width caused burnt marks in the prints?

· Why changing Line Width caused burnt marks in the prints?
If you increase the Line Width, what happens is that the printer extrudes more material than with the smaller line width. The additional material gets flattened out by the "shoulders" of the bottom of the nozzle tip (ie: the flat part of the bottom of the nozzle tip to the side of the nozzle hole). If you increase the Line Width too much, there some material may "curl up" beyond the shoulder and stick to the nozzle for a bit. Material that is kept at extrusion temperature for too long may carbonize ("burn"). If it does, and then gets pulled off the nozzle, you get the burnt mark.

Thank you. What happen when we reduce the Line Width? How come I also see burnt marks when reducing the Line Width to a value smaller than 0.4mm which is the size of my nozzle?
What is the best value for Line Width if I use a 0.4mm nozzle?

Cura 5.7 is here and it brings a handy new workflow improvement when using Thingiverse and Cura together, as well as additional capabilities for Method series printers, and a powerful way of sharing print settings using new printer-agnostic project files! Read on to find out about all of these improvements and more.
S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
(Sorry, was out of office when this released)
This update is for...
All UltiMaker S series
New features
Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.
