 This section controls the optional extruder homing step. The `extruder_homing_endstop` is either a real endstop name or the string "collision" which causes Happy Hare to "feel" for the extruder entrance.  If other options dictate this homing step it will automatically be performed, however it is possible to force it even when not strickly needed by setting the `extruder_force_homing: 1`.

 This section controls the module responsible for loading filament into and unloading from the extruder/toolhead. There are many options and the notes below and in the file explain the options already.  Note that the default of synchronized loading and non-synchronized unloading is recommended. Read about the loading and unloading sequences [here](https://github.com/moggieuk/Happy-Hare#---filament-loading-and-unloading-sequences).

 Happy Hare has the ability to synchronize various motors during printing operation and this section controls those options. Make sure you have [understand the caution](https://github.com/moggieuk/Happy-Hare#4-synchronized-gearextruder-motors) needed when `sync_to_extruder: 1` is enabled.
