Trouble printing PLA Tough

Bambu Lab P1 Series Troubleshooting
1

I’m mostly happy with my brand new P1S, but printing an AMS stand using Bambu Labs PLA Tough (grey) gives me a bit of a headache.

Settings:

  • pre-installed 0.4 nozzle
  • Cool Plate, glue stick, door and top opened
  • latest BambuStudio and firmware
  • 0.16 mm layer height, 5 top/bottom layers
  • 20 % gyroid with infill combination
  • 3 wall loops, Classic wall generator
  • inner-outer-infill order
  • default filament settings

The meh spots are not even where the seams (in the back) are. What am I missing?

Have you tuned the pressure advance (flow dynamics)?

I have, the Bambu Lab preset was already spot on.
