Is there an existing issue for this problem?

I have searched the existing issues

OrcaSlicer Version

2.3.2-dev

Operating System (OS)

macOS

OS Version

macOS 26.1

Additional system information

No response

Printer

Anycubic Kobra S1

How to reproduce

Slice anything on any printer
Switch to "Flow"
Read the message below while the print head is moving without extruding

Actual results

Slicer calculate flow based on speed: 23.64 mm^3\s which even more than max flow rate in filament settings.

Expected results

Because no filament is extruded during travel movements and Orca correctly identifies them as travel, the flow parameter is unnecessary and can be omitted or set to 0.0 mm³/s.

Project file & Debug log uploads

I uploaded the 3MF archive for formality, but based on my observations it is not actually needed. This issue occurs with any configuration and with any slicing.
