How to reproduce

In the machine's start gcode section, I have this:

START_PRINT BED_TEMP={first_layer_bed_temperature[0]} EXTRUDER_TEMP={first_layer_temperature[0]} MATERIAL='{filament_type[0]}' VOLUME={extruded_volume_total}

The issue is that extruded_volume_total is always zero. It is not calculating properly / populating the variable.

Actual results

extruded_volume_total variable is always zero, and can be seen in the exported gcode file.

Expected results

I would expect to see a number > 0 anytime I have sliced an object.
