extruder_stepper: Do not default to synching with "extruder" at startup
With recent changes, the extruder_stepper may be used for new purposes, and synchronizing to the "extruder" motion queue at startup may become a confusing default. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>

## Changes
|
||||
|
||||
20220304: There is no longer a default for the `extruder` parameter of
|
||||
[extruder_stepper](Config_Reference.md#extruder_stepper) config
|
||||
sections. If desired, specify `extruder: extruder` explicitly to
|
||||
associate the stepper motor with the "extruder" motion queue at
|
||||
startup.
|
||||
|
||||
20220210: The `SYNC_STEPPER_TO_EXTRUDER` command is deprecated; the
|
||||
`SET_EXTRUDER_STEP_DISTANCE` command is deprecated; the
|
||||
[extruder](Config_Reference.md#extruder) `shared_heater` config option
