To deal potential z scaling when fade is enabled, a fade_target option has been introduced. This option may either be set to 0.0 or any z position within the range of the mesh. A value of 0.0 will result in previous behavior, where z adjustment phases out until no further adjustment is added. A non-zero value will phase out adjustment until the target has been reached, after which the rest of the print will be offset along the z axis by the fade_target. By default the fade_target will be calculated as an average of the mesh.

Cheap mechanical servos have small flickering. When this servo stay on one position, this flickering slowly destroy internal potentiometer and make servo unusable. Many mechanisms need servo only to change position. Therefore I create this minor path to enable/disable servo. It stop pulses for this servo, that's all.
Corresponding G-code is:
SET_SERVO SERVO=config_name [WIDTH=] [ENABLE=<0|1>]
SET_SERVO SERVO=config_name [ANGLE=] [ENABLE=<0|1>]
For example:
SET_SERVO SERVO=touch ANGLE=80 ENABLE=1 ; enable servo and set position
G4 P200 ; wait 200ms
SET_SERVO SERVO=touch ENABLE=0 ; disable servo
This patch add one option to servo configuration:
enable: <False/True> # default True
It not have impact to user code existing already because it is optional parameter and default value is same as original behavior.

It appears the st7920 requires a longer delay when switching from
command to data mode (and vice-versa). Slower MCUs don't show a
problem because the klipper command processing time results in a
sufficient delay. However, some of the faster MCUs can process
klipper commands fast enough that the next st7920 transfer is sent too
fast. Add an additional delay to account for this.

The different uses of get_position() can be confusing, so choose a
different name for the ProbePointsHelper callback.

Move the trilateration algorithm to mathutil.py. It may be useful
outside of delta kinematics, and it complicates the delta code.

Add support for an itersolve_set_position() function that sets a
stepper position from a cartesian coordinate. This eliminates the
need for both the python and C code to be able to translate from a
cartesian coordinate to a stepper position.

Calculating the cartesian position from the stepper positions can be
complex and cpu intensive, so rename it to calc_position() to be more
descriptive.

After a probe operation, homing_move() will already have recalculated
the toolhead position. The get_position() method can be slow, so use
the already calculated position.

Update the code to use the term "rail" when dealing with a motor
controlled "axis". A rail has a series of steppers and endstops that
control that motor controlled "axis".

Add additional wrapper functions so that no outside callers need to
peak into the member variables of PrinterStepper.

All the kinematic code now uses the iterative solver to generate
steps. Remove the old stepcompress_push_const() mechanism.

Use the -fwhole-program option when compiling the host C code. This
makes it easier to support inlining across C files.

This change will make the "PROBE" command actually reply with the
z-position where the probe triggers. As this command is called
internally for the BED_TILT_CALIBRATE and Z_TILT_ADJUST those commands
will also give a response while probing, which I see as advantage over
the silent operation.
This change also lets one define some gcode for a repeatable probing
test to meassure the quality of the sensor and overall probing accuracy.

Added a config parameter to define the homing override axes. This way
one can still home x and y axis without the z-probe cycle coming in the
way.

Disable the verify_heater checks when debugging, as otherwise it can
cause failures when processing files in batch mode.

In some rare circumstances it was possible for the host software to
become so busy that it does not transmit a get_clock request for
several seconds. (In particular, this could occur with some complex
calls to coordinate_descent.) If that happened, it was possible for
the code to incorrectly report a "Timeout with MCU" error. Rework the
is_active() check to prevent that.
