cura - shell is missing from sections of vertical walls.

[keener 0]

I have a model that has a C shape 2mm wall of about 3cm tall.

Some sections of this wall look like they are missing their shell. I have printed the same gcode with ABS and PLA. The ABS version is in red and pla is blue in the photos. PLA is coming out nicer but it is still missing its walls shells at the same spots as ABS.  I am thinking the wall thickness of 0.8 is not respected at all times.

I'm using the Cura 2.3.1. I've also tried 2.4 beta and made the wall in my model thicker to 3mm from 2mm. But I'm still seeing the same thing happening.

Layer height is 1.2mm. (EDIT: Shell > Wall Thickness was 1.2mm and Infill Density was %50 in both attempts)

Any help is appreciated.

Thank you

I will post photos to this thread shortly.

Isn't PLA great? So that's underextrusion you are experiencing. Most likely printing too fast and/or too cold. What temp where you printing at for each material and what layer height, nozzle size and print speed were you at? Those 4 things combine to tell me if you should be able to print that kind of volume/second at a given temperature.
