| 9 | In order to use probing, you must configure the input for probing in the parameters of the input signals. | ||

| 11 | Issue the (% style="color:#a0be2d" %)//**G38.x**//(%%)// axes //command to perform probing. The axis parameters are optional, but at least one of them must be specified. All of the indicated axes define a point towards which movement is made during probing. If probing did not work before reaching the endpoint, commands (% style="color:#a0be2d" %)//**G38.2**//(%%) and (% style="color:#a0be2d" %)//**G38.4**//(%%) signal an error. | ||
| 12 | |||
| 13 | The movement to the endpoint during probing is carried out with the current feed rate and stops (subject to acceleration restrictions) when the endpoint is reached or when the probing input signal is expected to change, whichever occurs earlier. | ||

| 51 | If the P parameter is not specified, probing ends when any of the Probing, Probing2, Probing3 inputs fires. | ||

| 53 | Example of a probing macro for use with a sensor ZATS-01-NC. In this case, the sensor that works first (petals) is assigned to the Probing input, the second one (microswitch) is assigned to Probing2. | ||
