#5090 to 5094
Probing Cycle Positions
These parameters are read-only. They correspond to values (in the
machine coordinate system) generated by the last successful probing cycle.
These cycles are programmed using G-codes G38 (circle diameter and
center measurement) and G38.1 (parallel probing cycle).
