 ## Configuration
 
-The `[beacon_true_zero_correction]` module is enabled by default in RatOS whenever a beacon probe is configured. It can be configured by adding overrides in `printer.cfg` as follows:
+The `[beacon_true_zero_correction]` module is enabled by default in RatOS whenever a beacon probe is configured in the setup wizard. You should not add anything to your `printer.cfg` unless you want to disable the true zero correction feature.
 
-```properties
-[beacon_true_zero_correction]
-# If True, the true zero correction feature is disabled. Default: False
-disabled: False

-## Diagnostic Configuration
-
-The following configuration options are available for diagnostic purposes only. Users should not modify or paste these these settings into `printer.cfg` in normal use.
+### Disabling True Zero Correction
+ Add the following to `printer.cfg`:
 
 ```properties
 [beacon_true_zero_correction]
-# z values greater than z_rejection_threshold are rejected. These typically correspond to early triggering
-# of beacon contact before the nozzle has touched the bed. From test data, these are rare. Only 0.028% of samples
-# exceeded 75um (from over 32,000 samples across multiple machines and print surfaces).
-# Rejected samples are discarded and another sample is taken in its place at a different random location.
-# Default: 0.075, minimum: 0.03
-z_rejection_threshold: 0.075
-# Controls the sampling strategy, notably affecting the number of points probed.
-# - Level 1: 6 points probed, 1 zero sample, use mean of 3 minimal samples. This is the default and recommended level.
-# - Level 2: 10 points probed, 1 zero sample, use mean of 3 minimal samples. This is a more robust probing strategy.
-# - Level 3: 12 points probed, 1 zero sample, use mean of 3 minimal samples. This is the most robust probing strategy.
-# From extensive testing, level 1 is very effective and efficient, with levels 2 and 3 offering only very modest gains
-# and diminishing returns. Levels 2 and 3 are included for diagnostic purposes, but level 1 is recommended for most users.
-# The zero sample is the implied zero sample from the initial BEACON_AUTO_CALIBRATE invocation.
-sampling_strategy: 1
-# If True, each of the multiple probe locations will itself be probed several times using
-# the standard beacon error detection logic. From extensive testing, this mode offers no benefit
-# and should not be used. It is included only as an option for diagnostic purposes. Deafult: False
-use_error_corrected_probing: False
