Is there an existing issue for this feature request?

I have searched the existing issues

Currently, in OrcaSlicer (v2.3.2 and others), there is no simple way to define a maximum bridge length that can be printed without supports when using "Normal" supports. Users have to either support all bridges or none at all. This leads to wasted filament and time on short bridges that the printer could easily handle in the air.

Which printers will be beneficial to this feature?

Klipper, All

Describe the solution you'd like

Add a parameter like max_bridge_length_without_support in the Support tab.

If a bridge is shorter than this value, no supports are generated.

If it's longer, supports are generated as usual.

Describe alternatives you've considered

Currently, we have to use manual support blockers or modifiers, which is time-consuming for complex models.

Additional context

This would greatly improve the user experience for tuning PETG and PLA profiles where short bridges (e.g., <20mm) are fine, but long ones need a foundation.
