#bambulab #p1p troubleshooting report:

Symptoms:
▪️“Phfft” noise when bed is moved to the top limit of Z-axis (all the way up).
▪️Noise appeared to go away after the first couple layers (16mm setting) were cleared.
▪️ No obvious impact to printing or performance.

Troubleshooting:
▪️Restarted and swapped filament. No change. Moved bed and isolated sound to the back Z-axis rod.
▪️Discovered a blob of plastic that was pretty old sitting on the top of the moving platform. Suspect this was squishing, ejecting air in the tube-like shape, causing the “pfft” sound. See attached image.
