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 hits the bed, record the z position and Add that to your z offset.
Do you happen to know what setting that is? I figured that is what is going on but the only option I can find is Safe Z homing, but if I disable that when it runs G28 it does it in the corner of the bed so the probe never hits the bed.

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.
Please explain to me how to...
