Describe the solution you'd like

Why is internal bridge density capped at 100%?

Please allow it to exceed 100%, just like external bridges.

Through numerous experiments, I have discovered a setting that keeps the top surface flat even at higher density by increasing the nozzle temperature and utilizing bridge acceleration.

It works perfectly even with a bridge distance of 250mm.

I believe applying this to internal bridges would make "zero-infill" printing viable.

For your reference, here are my settings:
Nozzle Temperature: 230C
Bridge Speed: 50mm/s
Bridge Acceleration: 1% (A value that allows the speed to increase gradually, assuming the bridge length is equal to the bed width) (My bed size: 256)
Bridge Density: 120
Bridge Flow Ratio : 1.2
Thick Bridges: Enabled
