G-code Output Settings

Verbose G-code

Parameter: gcode_comments
Type: Boolean
Default: Disabled
Description: Add descriptive comments to the G-code output. Useful for debugging but increases file size.

Label Objects

Parameter: gcode_label_objects
Type: Boolean
Default: Enabled
Description: Include object labels in G-code. Enables features like "Cancel Object" on compatible firmware.

Output Filename Format

Parameter: output_filename_format
Type: Text template
Description: Template for output filename. Supports variables like {input_filename}, {layer_height}, {filament_type}, etc.

Available Variables

Variable	Description
`{input_filename_base}`	Model filename without extension
`{layer_height}`	Layer height value
`{filament_type}`	Filament type (PLA, PETG, etc.)
`{print_time}`	Estimated print time
`{filament_used}`	Filament used in mm
`{nozzle_diameter}`	Nozzle diameter
`{printer_model}`	Printer model name

Example Format

{input_filename_base}_{filament_type}_{layer_height}mm.gcode

Result: benchy_PLA_0.2mm.gcode

G-code Flavor

Parameter: gcode_flavor
Options: Marlin, Klipper, RepRapFirmware, Smoothieware, etc.
Description: The firmware dialect to use. Affects certain G-code commands and syntax.

Post-processing Scripts

Parameter: post_process
Type: Script path(s)
Description: Scripts to run on the G-code file after slicing. Can modify, analyze, or transform the output.

Use Relative E Distances

Parameter: use_relative_e_distances
Type: Boolean
Default: Enabled
Description: Use relative extrusion values (M83) instead of absolute (M82). Most modern firmware prefers relative.

Arc Fitting

Parameter: arc_fitting
Type: Boolean / Options
Description: Convert linear moves to arc commands (G2/G3) where possible. Reduces file size and can improve surface quality.

Firmware Compatibility

Firmware	G-code Flavor	Notes
Marlin	Marlin	Most common, Ender, Prusa
Klipper	Klipper	Requires specific features enabled
RepRapFirmware	RepRapFirmware	Duet boards
Bambu Lab	Marlin (BBL)	Specialized Bambu Lab variant

Tip: Enable "Label Objects" to use the "Cancel Object" feature. If one object fails during a multi-object print, you can cancel just that object and let the others continue.
