I haven't messed with firmware in a long time but i think it was something like min software endstop. Safe Z homing brings the print head to the middle of the bed for z homing.

Sounds like you dont have the setting in the firmware that allowes the z axis going into negative position. I havent done BLTouch yet but with a regular probe, you do G28, then G29. move z until it...
