G1 Z380 U380 V380 W380 F4000 S1 ; move up to 380mm in the +Z direction, stopping if the homing switch is triggered
So you are not homing Z using the BLTouch. In that case, the BLTouch should already be retracted when you start. If you want to make sure, you can put the M280 command to retract and/or reset the BLTouch at or near the end of config.g, or in homedelta.g.
A reminder: H corrections to the G30 probe points in bed.g should only be made if you have established that your Z probe has a different trigger height at different probe points (typically caused by effector tilt that varies with XY position).
I always presumed the firmware moved on to the next gcode as this was some sort of look ahead function given that at 2.5 deg C below the set heater temp, it was heading in that direction, so might as well save time and move on to the next command.
Ignore my message above, I got the wrong end of the stick.
