Strange print deformities?

Bambu Lab X1 Series
1

Hey everyone. First time poster!
So, I’ve been printing with my printer for around a month now and have had nothing but great results. Today, I’ve tried printing some smaller things and have seen the quality of the prints dip for some reason.

The main failure modes are as follows:
Pitting in certain spots
Print curling from bed

Filament: Bambu PLA Basic
AMS Dry box
Filament is not moist at all.
Bed is stock Cool Plate (with glue. Tried without glue and same issue.)

Slicer set to Bambu Lab PLA Basic (Modified with Aux fan set to 0%)

If anyone has any pointers, it’d be greatly appreciated.
Thanks!

Do you have the seem set to Random? That’s what those little pits look like.

That is bizarre indeed. It looks almost like your filament flow is at the edge of what it wants to extrude smoothly.

There is an experiment you can try to see if it affect the outcome. Try this:

  1. Increase the wall thickness by 1.
  2. In a separate experiment, try changing the wall printing order from the default of inner/outer and to outer/inner and see if that has an affect.image
  3. One more longshot might be to also change the infill anchor settings to something else. Use an extreme value to really set apart the two prints.

  4. And then last but not least. Leave everything alone and in your print, try placing the printer in quiet mode which will slow everything down to 50% speed. If that fixes it, then it often points to a filament flow problem and you may want to try to recalibrate both your flow rate or lower your max flow rate. You can also try changing the speeds in the speed menu.
