Hi,
download it and see for yourself.
The principle gain is the ability and capability to customize the way Mach4 behaves and presents itself. This comes
about in part due to Lua, the scripting language used by Mach4, which despite its simplicity manages to enable
some very powerful programming paradigms, and in part to the modular structure of Mach4.
Mach4 is designed and developed in a manner that makes it attractive to OEM customers and its ability to be customized
is critical, after all they are manufacturing machines and want the control software to reflect the unique design features
of the machine.
