Need to have the zero macro in the macro folder.
Copy the macro to a text (notepad) file and call it M615.m1s or some number not in use. Place this in the macro folder with the name of your profile (Mach3mill)
Then use the number 615 in the shuttle config. It is that easy.
Also what you should do is use this code for the on screen button. Code "M615"
