Printer: P1S

Slicer: Orca

Material: PLA

Temp: 230°c

Bridge Flow: 100%

Bridge Density: 114% (after testing with this tool: https://www.printables.com/model/1482067-bridge-density-experiments/files )

☝️ might be the main cause? Should I lower this for worse bridging?

Bridge Speed: 10mm/s (used to be 50mm/s, lots of sagging)

This was my third attempt for this print. At first I thought it was over extrusion when bridging, so I lowered bridge flow from 120% to 100%; then I thought it was heat shrinkage so I left 2 layers of 15% infills between top & bottom layers and that didn't help either.

What's the main cause for this deformation?

Update: I tried bridge flow 100% and bridge density 100%, worse bridging and more space for heat shrinkage didn't help.
