Marlin Configuration Options from the Command Line

These scripts edit Marlin/Configuration.h and Marlin/Configuration_adv.h in place. Run them from the repo root. Commit or stash your own edits first so the changes are easy to revert, or run buildroot/bin/restore_configs afterward (which does a git checkout of the config files, discarding uncommitted edits to them).

Find

buildroot/bin/opt_find LIN_ADV # enabled or disabled options matching the name buildroot/bin/opt_find -e BABYSTEP # only enabled buildroot/bin/opt_find -d BABYSTEP # only disabled

Enable / disable

buildroot/bin/opt_enable LIN_ADVANCE ADAPTIVE_STEP_SMOOTHING buildroot/bin/opt_disable ADAPTIVE_STEP_SMOOTHING

opt_enable exits with an error if an option can't be found.

Set a value

buildroot/bin/opt_set MOTHERBOARD BOARD_RAMPS_14_EFB EXTRUDERS 2

Takes <name> <value> pairs. An option that does not exist is added to Configuration.h.

Use example configurations

buildroot/bin/use_example_configs Creality/CR-10/CrealityV1

Fetches the named example from the Configurations repo (branch matched to your working branch, otherwise bugfix-2.1.x). Use release-2.0.9.4:Creality/CR-10/CrealityV1 to pick a branch or tag.

Tips

• Option names are matched exactly by enable/disable/set. Use opt_find first.
• Some options need others (see Marlin/src/inc/SanityCheck.h). A build error from a sanity check tells you what is missing.
• The CI test files in buildroot/tests/ use these same operations. Read a few as examples.
