For RepRap firmware, the "Filament used" gcode comment now lists values for all extruders.
For RepRap firmware, the "Filament used" gcode comment now lists values for all extruders.

The firmware expects the comment to look like this example:

; Filament used: 2.7m, 10.2m

i.e. the values are listed in extruder order separated by comma and space.

BTW - This PR does not affect Marlin gcode which uses the same string, should it?
