Cura 3.6 ignores any filament diameter setting

Recommended Posts

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

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
