M4 doesn't use VB Script.  You have to re-write the macro in Lua.

Hi CMARONEY...

You need copy this file to your Profile Macro folder in Mach3 (Attached file M25.M1S)

When you create your NC or TXT file to cut your part, in your plasma cnc machine just add before turn on the torch one line wit the me code M25

This is a NC File sample
