+### [temperature_probe]
+
+Reports probe coil temperature.  Includes optional thermal drift
+calibration for eddy current based probes.   A `[temperature_probe]`
+section may be linked to a `[probe_eddy_current]` by using the same
+postfix for both sections.

+#sensor_type:
+#sensor_pin:
+#min_temp:
+#max_temp:
+#   Temperature sensor configuration.
+#   See the "extruder" section for the definition of the above
+#   parameters.
+#smooth_time:
+#   A time value (in seconds) over which temperature measurements will
+#   be smoothed to reduce the impact of measurement noise. The default
+#   is 2.0 seconds.
+#gcode_id:
+#   See the "heater_generic" section for the definition of this
+#   parameter.
+#speed:
+#   The travel speed [mm/s] for xy moves during calibration.  Default
+#   is the speed defined by the probe.
+#horizontal_move_z:
+#   The z distance [mm] from the bed at which xy moves will occur
+#   during calibration. Default is 2mm.
+#resting_z:
+#   The z distance [mm] from the bed at which the tool will rest
+#   to heat the probe coil during calibration.  Default is .4mm
+#calibration_position:
+#   The X, Y, Z position where the tool should be moved when
+#   probe drift calibration initializes.  This is the location
+#   where the first manual probe will occur.  If omitted, the
+#   default behavior is not to move the tool prior to the first
+#   manual probe.
+#calibration_bed_temp:
+#   The maximum safe bed temperature (in C) used to heat the probe
+#   during probe drift calibration.  When set, the calibration
+#   procedure will turn on the bed after the first sample is
+#   taken.  When the calibration procedure is complete the bed
+#   temperature will be set to zero.  When omitted the default
+#   behavior is not to set the bed temperature.
+#calibration_extruder_temp:
+#   The extruder temperature (in C) set probe during drift calibration.
+#   When this option is supplied the procedure will wait for until the
+#   specified temperature is reached before requesting the first manual
+#   probe.  When the calibration procedure is complete the extruder
+#   temperature will be set to 0.  When omitted the default behavior is
+#   not to set the extruder temperature.
+#extruder_heating_z: 50.
+#   The Z location where extruder heating will occur if the
+#   "calibration_extruder_temp" option is set.  Its recommended to heat
+#   the extruder some distance from the bed to minimize its impact on
+#   the probe coil temperature.  The default is 50.
