Pitting on surface finish

[jeffhuber]

Not sure how else to describe this. I am getting pitting on the surface of the print. The weird thing is that I printed this with 0 retraction! (because I thought the issue was retraction). I'm using Cura to slice. any ideas?

Air bubbles in the filament?

If it was trapped moisture, I wouldn't expect the rest of it to look so nice.

it feels like 1 per layer - and often times they will "stack up" and be at the same place

so i doubt it's that :/

Does it happen with other slicers too?

[jeffhuber]

havent tested that yet! good question though - i will try that

Printing with Slic3r seemed to help the problem (although it introduced others). I vastly prefer Cura for surface finish. anyone have experience with Cura and what might cause this or what to tinker with?

Do you here pops when printing? This looks a little like the problems I had when I got a bad roll of filament with moisture problems. I dried it out in a ziplock storage bag with one of those silica dehumidifiers and it started printing OK again.
