Okay, I knew it. I was totally overthinking. I simply do G38.3 to the sensor. set it as Z home do touch up on my stock zero and after changing the bit again G38.3 and Z home. Can I somehow home G53 from MDI to use it in macro or clicking on axis gui is the only way? 
Run 3
 

In Mach3, the G53 command is used to move the machine to its machine coordinate system zero. To use G53 in a macro or through the MDI (Manual Data Input) interface, you can follow these steps:

1. Open the MDI interface in Mach3.
2. Type the following command: G53 X0 Y0 Z0
   This command will move the machine to the machine coordinate system zero position.
3. Press the Enter key or click the "Send" button to execute the command.

Alternatively, if you prefer to use the GUI (Graphical User Interface) to home the machine to the machine coordinate system zero, you can follow these steps:

1. Open the Mach3 interface.
2. Click on the "Ref All Home" button on the main screen.
   This button will initiate the homing sequence and move the machine to the machine coordinate system zero position.
