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.

Instead of requiring the user enter velocity and accel parameters for
extrude only moves, calculate sane defaults from the printer's maximum
velocity and accel.

Be more clear on which parameters have defaults and which parameters
must be specified in the config.

On a delta printer, z moves require the mcu to support the greatest
number of steps per second. However, z moves are rare, so it makes
sense to limit the velocity of z moves separately from the velocity of
normal xy moves.

Change the config file so the maximum accel and velocity are specified
in the "printer" section instead of the individual "stepper" sections.
The underlying code limits the velocity and accel of the toolhead
relative to the print object, so it makes sense to configure the
system that was as well.

Invert the default meaning of the stepper direction pin. Instead of
treating a low value as position motion, treat a high value as
positive motion. This matches what other firmwares do, and it matches
what common stepper motor drivers document.

A pullup setting on an input pin (ie, '^') should enable the hardware
pullup resistor, but it should not invert the trigger level (ie, it
should remain trigger on high). Those that need to change the trigger
level (ie, trigger on low) must now do that explicitly (ie, '^!').
This makes the code match what other firmwares do.

Allow a config file to specify 'min_extrude_temp: 0' to disable the
minimum extrude temperature test. This makes it easier to perform
testing on the avr simulator.

Allow the config file to specify the minimum temperature for the
extruder and check for that temperature prior to moving the extruder
motor.

Add support for enhancing the precision of endstop switches by also
inspecting the phase of the stepper motor when the endstop triggers.

Add a config option to define an amount of additional filament to feed
into the extruder during acceleration and deceleration of the
extruder. This can help ensure plastic is deposited in the correct
places during a print.

Create a new python file (extruder.py) to control the extruder heater
and stepper motors. This separates the extruder control logic from
the cartesian robot code - making it easier to customize both the
kinematic control of the robot as well as the extruder.
