The BLTouch is hitting the bed on the double-probing
First, make sure to check if stow, deploy and the trigger are working correctly.

Second, check the pins files to make sure you put it in the correct pins. Black and White probe pin might need to go to Z-min or probe pin depending on. Make sure to check that.

Third, add "BLTOUCH delay". It might be triggering too slow or too fast for the next one to react. So after the first trigger, there should be a time for it to "re-setup" for the second. But if there is no time to do that then it won't trigger. 

To add examples: If you have SKR 1.4 Turbo, then use BLTouch probe pins (black and white) on the board. IT will NOT recognize. You have to use Z-min endstop pins. Reason for this?:

#define Z_MIN_PROBE_USES_Z_MIN_ENDSTOP_PIN


If this has been used, Z-min probe will use Z-min endstop pin instead of Z-min probe.
