Help fixing PLA Silk+ print (Pitting issue)

I’m sure I’m missing something relatively simple to fix this, but when printing with Bambu PLA Silk+, it is constantly making little pits on the outer wall.

I’ve had this issue with non-bambu Silk previously, and was able to correct it by adjusting the print temps and retraction length and speed. However, none of these seem to be helping with Bambu’s Silk+

What I’ve tried:
Print Temp: 210-230 in 5 degree increments
Retraction Length: 0.6-1.4mm in 0.2m increments
Retraction Speed: 30-80mm/s in 10mm/s increments
Print speed: 40-150mm/s (40, 50, 60, 80, 100, 150)
The prints were split between 2 different X1C’s, just incase there was a funky calibration/hotend issue on 1 printer, same results from both

Moisture: 6hr in Sunlu S4, rotated every 2hr, and burped the box to let moisture out when rotating - Did this a second time as well (12hr total)

Seam: Set to aligned, no random seams here!

At this point I’ve used 25% of the roll just printing test cubes, so any ideas would be appreciated


For silks, drying is important as youve noted, and I think you’re close with the retraction. Go even less IMO. On an elegoo centauri carbon I use 0.4 retract length for a specific silk I have [iBoss].

Can’t hurt to try! I’ll go down to 0.3 retraction length
I’ll run it warm for this test, 230 at 40mm/s outer wall

That’s got it! Thank you!
