Store the pressure_advance value in "struct extruder_stepper" instead
of in the trapq's "struct move". This makes it possible for multiple
stepper motors to have different pressure advance values while still
using the same trapq.

Convert stepper.get_past_commanded_position() to the more general

Sometimes an automated filament load is implemented,
but extruder might not always extrude filament.
This adds a flag to check if this operation is possible.

Pass a print_time instead of a clock to get_past_commanded_position().
Fix calculation on steppers that home and use an inverted direction
pin.

The min_stop_interval safety check is fragile and leads to a notable
amount of complexity. Avoid these issues by not programming this
safety check.

Introduce a heaters.set_temperature() command and call that from
commands that set a heater temperature. This new function calls
toolhead.register_lookahead_callback() so that the idle_timeout gets
notification that activity has occurred.

The stepper positions will only be in sync after the step generation
code has been flushed. This fixes an "internal error in stepcompress"
error during a SYNC_STEPPER_TO_EXTRUDER command.

Update callers to use the printer.command_error reference instead of
directly using homing.CommandError() when raising or catching errors.

There's no reason to distinguish between an EndstopError and a
CommandError, so just use CommandError.

Rework extruder.get_trapq() into extruder.sync_stepper() so that
extruder_stepper.py does not need to directly access the extruder

Rename try_load_module() so that it uses consistent naming for
"printer objects". Change the function to raise an error by default

The heater logic is an independent module that does not need to be

The print_time parameter of heater.set_temp() is not currently used
and it isn't necessary to flush the look-ahead queue just get the
print_time. Remove the parameter from heater.set_temp() to avoid
flushing the look-ahead queue.

The builtin Tn command is not sufficiently flexible to control some
multi-extruder printers. Remove the command and encourage users to
define individual gcode_macros for each Tn instance.

Implement the pressure advance calculations while performing the

Support averaging the extruder position over a time range to "smooth

Add support for kinematic functions that calculate step times based on
a range of the motion queue. This requires adding additional pause
times when fully flushing the motion queue.

Directly disable all the stepper motors on a global motor_off() from

No longer allow the primary extruder to be named "extruder0". This

Do not apply max_extrude_cross_section check, and do apply

Calculate the ratio of axis distance to total move distance (axis_d /

Allow an arbitrary gcode_id to be supplied during heater setup. This allows future extras to register additional IDs beyond B, and T#.

Some users increase max_extrude_cross_section to avoid issues with
some slicers. However, increasing that value also increases the
defaults for the max_extrude_only parameters which is not obvious.
Base the max_extrude_only defaults only on the configured nozzle
diameter.
