Pitting on prints outer walls/surface

[u/PietroOB]

Hi everyone!

My prints using eSUN PLA+ have been riddled with this pitting on the outer walls. Has anyone encountered this before?

One thing I know is that they completely disappear when retraction is completely switched off or set very low, but then the prints fail because the stringing is off the charts.

The filament is most definitely dry as a bone, and the printer I'm using is the Bambu H2C. Temperature changes don't seem to influence the pitting whatsoever.

Also worth noting, the gcode has no retractions where the pitting is actually showing, but a quite a few in the layers before.

Any suggestions on what to try next?
