[FR] Ignore runout mm distance on print start with triggered runout sensor #26906

Did you test the latest bugfix-2.1.x code?

No, but I will test it now!

Bug Description

When FILAMENT_RUNOUT_DISTANCE_MM is defined and a new print is started without filament Marlin will be printing for the set FILAMENT_RUNOUT_DISTANCE_MM before stopping. However, when FILAMENT_RUNOUT_DISTANCE_MM is not defined, Marlin will immediately ask for filament change.

Bug Timeline

No response

Expected behavior

I'd expect Marlin to avoid starting a new print at all.

Actual behavior

Marlin starts to print till FILAMENT_RUNOUT_DISTANCE_MM is reached.

Steps to Reproduce

Define FILAMENT_RUNOUT_SENSOR and FILAMENT_RUNOUT_DISTANCE_MM (let's say 5) with all of the required defines.

FILAMENT_RUNOUT_DISTANCE_MM is working as designed, so I’ll convert this to a feature request.
