You can already include the individual extruder statistics in your output file using post processing commands and the existing variables.
Try inserting the following variables in the post processing section of the scripts tab using the PREPREND command and you will notice these stats appear in the beginning of the gcode
Code: Select all
{PREPEND "; total filament wg = [total_filament_weight]\n; T0 filament wg = [extruder0_filament_weight]\n; T1 filament wg = [extruder1_filament_weight]\n; total filament cost = [total_filament_cost]\n; T0 filament cost = [extruder0_filament_cost]\n; T1 filament cost = [extruder1_filament_cost]\n; total filament used = [total_filament_used]\n; T0 filament used = [extruder0_filament_used]\n; T1 filament used = [extruder1_filament_used]\n"}
More on the scripts tab can be found here
As always, I've documented your interest in this being improved inside the GUI and look forward to monitoring this topic for more ideas from all interested users.
Thanks for your great feedback!
