Macro Configuration

Macro Configuration (mmu_macro_vars.cfg)

This is where you'll likely spend most of your time tuning the MMU after the initial setup is done. It allows for configuration of all the supplied default macros in one place.

You will need to consult the Configuring mmu_macro_var.cfg reference page for full details, but essentially the file is broken up into sections where each section contains the configuration for the respective macro. These include:

Section	Macro Filename	Description
_MMU_SOFTWARE_VARS	base/mmu_software.cfg	Controls the behavior of the print start and finalization
_MMU_STATE_VARS	base/mmu_state.cfg	Customization of behavior when state changes
_MMU_LED_VARS	base/mmu_leds.cfg	Configuration of LED actions
_MMU_SEQUENCE_VARS	base/mmu_sequence.cfg	Control the movement of the toolhead during a tool change
_MMU_CUT_TIP_VARS	base/mmu_cut_tip.cfg	Controls the tip cutting procedure
_MMU_FORM_TIP_VARS	base/mmu_form_tip.cfg	Control Happy Hare's implementation of tip forming
_MMU_CLIENT_VARS	optional/client_macros.cfg	Customization of Happy Hare's pause, resume and cancel_print macros
