Total garbage quality prints with P1S

EDIT: below problem appears to be a fan issue. reseated the fan and can audibly confirm it's now working whereas earlier today when I printed the attached vase it wasn't. Reddit to the rescue! 🤯

Hoping for some help. P1S owner here... I'm about to toss out the printer since Its unworkable. Been getting inconsistent quality prints since I got it about a month ago. I have already used up two spools testing all sorts of settings I have mostly found on reddit but nothing works consistently.

I printed basic PLA and Silk PLA, both BBL own filament.

  • The printer is standing on a solid floor, on the anti vibration feet.
  • I have calibrated my printer a lot of times. both flow dynamics and flow rate
  • Nozzle used is the standard 0.4 version that comes with the printer
  • Tried every speed thinkable (Silk PLA the slowest by far)
  • Textured plate
  • Nozzle temp is 220degs
  • Flow ratio is 0.98
  • Max Volumetric speed 21mm3/s

When I slice a vase, all looks fine but when I print it's hit or miss. I can do two print jobs in a row and one can come out fine while the other is garbage. Same settings, filament etc etc.

I'm slicing with Bambu Studio;

  • Printing the outer wall at 200mm/s, inner wall 350mm/s
  • Layer height 0.12mm (initial layer 0.2)
  • Order of walls: changed to outer/inner (read that somewhere)
  • Retraction changed from 0.8 to 0.5

Starting to get really annoyed with the thing. Anyone any clues??
