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.

This allows SX1509 pins to be used as temperature fans and heater fans. Heaters are still disallowed.

The atmega328p is basically the same as the atmega328 - add explicit
support for it so that avrdude doesn't complain while flashing.

Commit 459e5219 added a special case to the boundary checks to permit
homing moves. In some cases, the second home retract could also be
outside the normal boundary checks - extend the special case to also
permit that move.

The gitdir previously could be absent and produce a version of "" in
spite of checks for it. Fixed.
Parent directories with shlex-interpreted characters in their names
could be misinterpreted. Removed shlex parsing.
Packagers may want to remove the git history to slim down the package
size, so add an option for using a file 'version' in the klippy
directory to set version without using git.

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.

The Trinamic stepper motor drivers are capable of reporting the

enddstop_phases module.

The Python 2.x ConfigParser doesn't support stripping of trailing '#'

Only clear the internal sync_print_time flag if the code performs a
regular "lazy" flush of the look-ahead queue. This helps build the
look-ahead queue even when running internal scripts.

Now that "Klipper state" messages are proactively sent, it is

When a delta printer has different arm lengths or different endstop
positions then the homing position falls outside of the normal
printable area. Add a special check to the range checking code to
permit this move instead of homing to a position near the actual
homing position.

Commit b0d859f2 introduced a second_homing_speed parameter, and it
also changed the retract speed. Revert the retract speed change (use
homing_speed when the head retracts).

Use the xor capability of the display to animate the glyphs, which
reduces the number of glyphs needed from 4 to 2. This should make it
easier to add future animations if desired.
