Enumeration Type Documentation

FilamentLoadState

enum modules::globals::FilamentLoadState : uint8_t

Different stages of filament load. Beware:

• the firmware depends on the order of these values to check for various situations.
• the unit tests abuse the bitmask-like values to check for multiple situations easily

Enumerator
NotLoaded	not loaded in the MMU at all
AtPulley	loaded to mmu (idler and pulley can grab it)
InSelector	'P1' loaded in selector (i.e. unsure where the filament is while doing some operation)
InFSensor	'f1' loaded into printer's filament sensor
InNozzle	'f2' loaded into printer's nozzle
