BLTouch calibrated, nozzle still dives into the bed

I have calibrated it several times using different methods and get the nozzle being 1.3 mm lower than the BLTouch pin so a Z offset of -1.3 mm. This works fine for auto homing, bed levelling and using code G1 Z0 to lower to where needed. However when using Cura to print the nozzle homes exactly as it should then drives the nozzle in to the bed ...
