[BUG] 2.0.9.2. breaks Sensorless Homing in combination with DELTA_AUTO_CALIBRATION

[Vabe7]

Bug Description

Using the Standard Kossel Mini Configuration the compilation fails if SENSORLESS_HOMING and DELTA_AUTO_CALIBRATION are both enabled. It fails with Marlin\src\gcode\calibrate\G33.cpp:76:28: error: 'probe' was not declared in this scope.

Configuration Files

Configuration.zip

Steps to Reproduce

Download 2.0.9.2 or latest bugfix, download Kossel Mini configuration, set driver to TMC2209, enable SENSORLESS_HOMING, DELTA_AUTO_CALIBRATION, PROBE_MANUALLY and disable Z_PROBE_ALLEN_KEY and Z_MIN_PROBE_USES_Z_MIN_ENDSTOP_PIN.

Expected behavior:
Should compile like in 2.0.9.1.

Actual behavior:
Fails with before mentioned error message.

In Marlin/src/gcode/calibrate/G33.cpp is

void ac_home() {
  endstops.enable(true);
  TERN_(SENSORLESS_HOMING, probe.set_homing_current(true));
  home_delta();
  TERN_(SENSORLESS_HOMING, probe.set_homing_current(false));
  endstops.not_homing();
}

This seems wrong to me... SENSORLESS_HOMING has nothing to do with having a probe...

Seems like it should be

void ac_home() {
  endstops.enable(true);
  TERN_(SENSORLESS_PROBING, probe.set_homing_current(true));
  home_delta();
  TERN_(SENSORLESS_PROBING, probe.set_homing_current(false));
  endstops.not_homing();
}

Certainly compiles now

Give this a try

This is a marlin issue though, not a config issue...

Seems to have been introduced here MarlinFirmware/Marlin#21899

I've created a PR to fix this issue, since this is not a issue with the Configuration files I am closing this issue.. But the fix should be applied to marlin shortly.
