      Is there a way to get the measured/calculated value that the probing came up with?
      The documentation says, “probing is repeated until two consecutive probe attempts produce results that differ by no more than the S parameter; then the average of those two results is used. However, if the number of attempts specified by the A parameter is reached without getting two consecutive results within tolerance of each other, no further probe attempts are made and the average result of all the attempts is used.”
      I would like to be able to get the value that is being used (especially after a failure to get 2 consecutive ones in a sequence of nnn attempts).

        @charames are you asking about the G29 mesh? You can look at the heightmap.csv to see the results if it finishes.

          oh, right... I do realize that I can get the average of 2 successful back-to-back probes by reading the heightmap.csv, but that won't tell me what value I have just measured as result of a home-z, for example. I want to be able to do some programmatic analysis before I allow a job to kick off using the measurement/calculation that the home command just came up with.

            Maybe an option:
