9. When the sensor has triggered and is flashing: [`M280 P0 S160`](https://marlinfw.org/docs/gcode/M280.html) (reset position from BLTouch)
10. [`M114`](https://marlinfw.org/docs/gcode/M114.html) = Determine and remember the current position of the nozzle! (e.g. Recv: X:40.00 Y:40.00 Z:1.30 E:0.00 Count X:3200 Y:3200 Z:520)
11. [`G90`](https://marlinfw.org/docs/gcode/G090.html) (Turn on absolute positioning)
12. [`G1 X38 Y15 F4000`](https://marlinfw.org/docs/gcode/G000-G001.html) (move the BL Touch Sensor to the exact same position where the nozzle was before)

17. Subtract point where BL Touch Sensor triggered (16) from point where nozzle touched bed (10) -> 1.30 - 0.7 = **0.6mm** -> That is our Z offset.
18. [`M851 Z-0.6`](https://marlinfw.org/docs/gcode/M851.html) (Save Z offset. Caution! Negative sign!)
