G-Code Postprocessor

Modular G-Code postprocessor for Prusa/SuperSlicer

Installation

Clone this repository git clone https://github.com/vertexbz/gcode-postprocessor.git

Provide path to ./run.sh file of the cloned repository in Print Settings > Output options > Post-processing scripts of your slicer

Configuration

Log level

Log level / verbosity can be used by providing -v (or --verbose) CLI flag, multiple use increases verbosity

Levels

• Default: Error
• v: Info
• vv: Info, long format
• vvv: Debug
• vvvv: Debug, long format

Config files

Default configuration is available in and loaded from ./config.default.yaml
User defaults can be provided via ./config.yaml (or ./config.yml) this file is not part of this repository, default one can be used as template
Defaults are overriden by file provided via -c (or --config) CLI parameter

Dry run

Dry run mode fully processes the input but doesn't save the output to file

CLI	YAML
-d --dry --dry-run	dry_run: True dry-run: False dryRun: true dryrun: false

Macros

Features look for popular custom macros which names may vary
Default configuration file contains full list of used macros

CLI	YAML
-m print_start=HELLO_THERE --macro print_end=BYE_BYE	macro: print_start: MY_CUSTOM_START_PRINT print_end: MY_CUSTOM_END_PRINT

Features

To have actual benefit from using postprocessor, desired features have to be enabled, via configuration file or with CLI flag

• Features can be specified multiple times, with same or different configurations
• Features are applied in the order provided, first config files, then cli
• Configuration file features configuration overrides previous ones, CLI specified features are appended

CLI	-f start-xy -f pa-extruder-fixer --feature start-xy --feature feature-with-config=option1=value,other_option={options_option=1}
YAML	feature: - pa-extruder-fixer - start-xy - feature-with-config: option1: value other_option: options_option: 1 to clear all prior features feature: []
