Additional notes
----------------
* This feature is most useful on delta printers and on the Z endstop
of cartesian/corexy printers. It is possible to use this feature on
the XY endstops of cartesian printers, but that isn't particularly
useful as minor differences in XY position rarely impact print
quality. It is not valid to use this feature on the XY endstops of
corexy printers (as the XY position is not determined by a single
stepper on corexy kinematics). It is not valid to use this feature
on a printer using a "probe:z_virtual_endstop" Z endstop (as the
stepper phase is only stable if the endstop is at a static location
on a rail).
* After calibrating the endstop phase, if the endstop is later moved
or adjusted then it will be necessary to recalibrate the endstop.
Remove the calibration data from the config file and rerun the steps
