Print error - stringy holes

Here could be a lot of solutions.
It seems that just the first layer is stringing at the holes,- right?

This means your bed calibration is not good enough for your print settings.
I would suggest you to slower your 1st layer speed,- make a custom profile and ride the first layer at 12mm/s instead of 18mm/s. Maybe give the material a bit more heat (+5°C).

The easiest way to figure problems out is to watch the print when your issue happens.- Then you would see, aahhh, bed adhesion.

Such problems could also cause:

  • print or bed temperature is too low
  • print speed is too fast

Right picture, hole near the hole:

I see there is a kind of under extrusion, i would recommened you to improve your linear advance (also called K-factor), see in this post :slight_smile:Improving Print Quality - #13 by C.Harris

Hope this helps!
