What's the setting to fix this under-extrusion at the z-seam?

I've been struggling with printing a calibration cube recently on Cura 4.12.1 on Windows. Wherever the z seam happens, there's an under-extrusion issue. I'll attach some pictures to show what I'm talking about.

 

  • If I randomize the z-seam it becomes less obvious, but it's still there.
  • I can disable retraction entirely and it's still there, so it's not a retraction issue.
  • If I use Prusa Slicer for the same STL, I don't get this issue, so it's not an STL problem.
  • I've tried different temperatures (from 190C to 220C) and it doesn't matter - it's not a temperature issue.
  • I've tried different filaments (different colors and brands) and it doesn't matter - it's not a material issue.
  • I've tried both the default standard (0.2mm layer) and dynamic (0.16mm layer) profiles and it doesn't matter.

 

I do have a direct drive extruder and an all-metal hot end, so retraction values are shorter (due to direct drive) and temps are usually hotter (due to the hot end) but, again, based on the tests I've done it doesn't seem to matter.

 

Is there some setting I'm missing that has to do with z-seam and reduced flow rate? Is it related to this gap in the z-seam topic?

    This cannot really be answered without knowing what settings you currently use. For example, if coasting is turned on, turn it off.

     

    Here's a small bit of general tips, from the Settings Guide plugin:

        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.
