Hi,
not quite sure what you guys are on about, files of type .m1s are for Mach3. This is a Mach4 board.
Lua source files are of type .mcs and compiled Lua files are of type .mcc.
Additionally its normal in Mach3 to have an M6Start script but not so in Mach4.
If your script is compiled VB then it won't run in Mach4.......Mach4 uses Lua 5.3 for scripting.
