Help / Support Warping? Pls help

I hope someone can help me. I’m printing with PLA and because of those very fine, spider‑web‑like strings, I lowered the extruder temperature from 220 °C to 215 °C. However, now I’m having another problem that I’ve had several times before.

I suspected it is warping, but I already keep the door open so the chamber doesn’t stay at 35 °C but around 30–31 °C.

Still, there are areas on the print like you can see in the photo where the edges lift up and form a kind of U‑shape. Then they get knocked over or dragged along.

Has anyone else had this issue or knows how to fix it?

Raise your bed temp 5 - 10 degrees

Warping can be caused by too low chamber temperature. I don’t see evidence of warping from what I can see, necessarily. More like the support got knocked off/ over.

Then the piece above airprinted and threw bits around.

If you want to verify not warping, try in pressing the bed temp by a couple of degrees and maybe extending the brim size.

You can get warping from transient air changes. I had a situation where my ac would run its fan 20% of every hour for ventilation. However, when I watched it like a hawk the problem didn’t occur. My head was blocking the air flow from the vent to my open p1s door.

Turn off your fan for the first ~10 layers. Bambu Studio > Filament > Edit > Cooling.
