The offset of the sensor is X=**-2** Y=**-25** and Z=**0**. These values ​​are already set as a standard. For other BLTouch mounts like the X-Carriage the values ​​would be e.g. X=29 Y=-15 and Z=0. However, all of this can be adjusted later via GCODE. The offset of the sensor is X=**-2** Y=**-25** and Z=**0**. These values ​​are already set as a standard.

### Wiring ### Wiring for MEGA M/S/X
The wiring is comparatively simple, since the i3 Mega (M/S/X) already has an unused sensor pin. Since ground can also be tapped, you only need two soldering points on the small hotend board. Here you can simply solder the supplied 2-pin header. The wiring is comparatively simple, since the i3 Mega (M/S/X) already has an unused sensor pin.

### MEGA Pro wiring
The user [Stefan Kalscheuer](https://github.com/stklcode) draws my attention in [this ticket](https://github.com/knutwurst/Marlin-2-0-x-Anycubic-i3-MEGA-S/issues/210) to the fact that the wiring of the MEGA Pro is different and he has documented two solutions to elegantly connect the BL Touch Sensor to the MEGA Pro. The free "X-Stop" connection can be used if you either change the two lines **A5** and **B5** in the upper green connector, or change the `Z_MIN_PROBE_PIN` (2) to the` X_STOP_PIN` (3) in the source code.

One of the servo extensions is led out past the top of the board. So that nothing gets stuck. There is enough space in front of the connector for the cable. The circuit board can then be screwed tight: One of the servo extensions is led out past the top of the board. So that nothing gets stuck.
