Bambu Lab P2S Spaghetti Due to Auxiliary Fan Overcooling

To determine if the auxiliary fan is causing premature cooling and subsequent warping, monitor the print's corners during the first 20 minutes of operation. If the edges of the model begin to curl upward while the auxiliary fan is running at high speed, the localized temperature gradient is likely causing the material to shrink and detach from the build plate. Confirm this by checking the slicer's active fan speed settings during the print.
