If configuring this value on a "clone" or older BL-Touch device, be sure to test the probe accuracy before and after setting this value (use the `PROBE_ACCURACY` command to test). +Multi-probing without stowing +============================= + +By default, Klipper will deploy the probe at the start of each probe +attempt and then stow the probe afterwards. This repetitive deploying +and stowing of the probe may increase the total time of calibration +sequences that involve many probe measurements. Klipper supports +leaving the probe deployed between consecutive probes, which can +reduce the total time of probing. This mode is enabled by configuring +`stow_on_each_sample` to False in the config file. + +Important! Setting `stow_on_each_sample` to False can lead to Klipper +making horizontal toolhead movements while the probe is deployed. Be +sure to verify all probing operations have sufficient Z clearance +prior to setting this value to False. If there is insufficient +clearance then a horizontal move may cause the pin to catch on an +obstruction and result in damage to the printer. + +Important! It is recommended to use `probe_with_touch_mode` configured +to True when using `stow_on_each_sample` configured to False.
