Cura 3.6 ignores any filament diameter setting

[SlyCat 0]

After trying to diagnose my under-extrusion issues I decided to see if the problem could be software side

I opened the calibration cube stl, saved the gcode file

Then changed the diameter of the filament (in material profile manager & machine profile manager, as my filament is actually 1.73mm) and saved as a second gcode

When I compared the two gcode file they are identical to each other

Even the amount extruded, in terms of length, does not change with either of these two filament diameter parameters being changed

 

Used the Ender3 & CR-10 printer profiles with the stock Normal and Fine setting profiles, yield the same results

Reinstalled 3.6 and the problem persists

 

Only option to mitigate this was to install the PrinterSettings plugin and set the diameter from there, but it is not ideal as it does not follow what the material profile diameter is (i'd have to reset this number any time I change material profiles)

 

Hoping some users could shed some light or further confirm this bug

I have noticed the same.
Slicing the same part, without changing anything other than the define material filament width does not alter in anything the gCode.

I'm not sure what is the intended purpose of that value but I'd expect we could fine tune the filament width using it.

Kept searching and found a way to go around this like some other slicers.
There is a "Flow" param under the settings for the material, is hidden per default, this should allow to compensate for (usually) thinner filaments.

Hey,

I solved the problem by making my own material definition. Set diameter of your own material to 1.25 mm.

Maybe this works.
